Unfortunately, Apple limits compatibility to Apple brand adapters (even though they use the same ASIX chipset). And it fails on non-Apple adapters in a confusing way: it will show as “Connected” in the Network control panel, but connections out won’t work — you’ll notice it has a self-assigned IP address (169.*), no router, and no DNS server. It looks something like this:

Fortunately, ASIX has an updated driver which works on Lion (and older versions). Note that if you had done this before upgrading to Lion, your old driver may be 32-bit. Lion moves all systems to a 64-bit kernel, so in the case of a Lion upgrade, you may have to uninstall the old driver (uninstaller included in the driver package), and follow the steps below to get ASIX’s latest driver.

Download the Plugable USB2-E1000 (ASIX 88178 chipset) driver.

If you’re downlading with Safari, look for the Download folder the Lion has in your Dock by default. Click on that to bring up recent downloads, which looks like this:

Open that folder, then click on the “.dmg” to open the ASIX driver installer disk image.

The image then shows up on the left side of the window, below your other drives, called “DISK IMAGE”. Click on this to open the image, then click on the installer (the icon with the package opening).

You’re finally out of Lion’s folders and into the installer proper.

The ASIX 88178 driver isn’t big (254K)

You will be prompted to let the driver install.

A reboot is required for the newly installed driver to be active.

After the reboot, if you open the Network control panel, you should now see “Connected”, but now also with a properly assigned IP address, DNS, etc.

If that’s not the case (or something goes awry later), it’s common on Mac OS X to need a fresh interface for the adapter, which you can create via the network control panel (this creates a new, clean configuration for an adapter). See the ASIX Mac installation guide for details.

And once you have that automatically assigned IP address, you should be done – open Safari and enjoy!

• If you want to verify that the adapter and the driver were installed properly click here

Connect the device to the Mac. Once connected click on the Apple icon and on ‘About This Mac’

Click on ‘More Info…’

Click on ‘USB’ on the left and on the ‘USB-Serial Controller D’
If all is well you should be seeing something like this:

Time to get the driver! Fire up Safari and browse to http://plugable.com/drivers/prolific/ and scroll down to Mac.
Click on the ‘PL2303 MacOSX10.6 dmg v.1.4.0.zip’, the Safari Downloads window should come up:

Double click on the md_PL23-3_MacOSX10

Now double click on the PL2303_1.4.0.dmg to mount the image

Now double click on the PL2303_1.4.0 to start the installation

Once the installer comes up click ‘Continue’ to proceed.

Then ‘Select a Destination’ click on your desired drive and click ‘Continue’ to move forward

Now just click ‘Install’ to continue.

You may be asked of your username and password – enter them and click ‘OK’

You’ll get a warning about restarting the computer after the installation is complete. This is normal, click ‘Continue Installation‘.

Installing should start (takes a couple of minutes to complete)

When it’s done you should see this:

Click on ‘Restart’ to reboot the Mac.

 After you restart, check that everything has installed OK.
On the Mac there are two methods to determine this:

Method 1:
Click on ‘Applications’

Click on ‘Utilities’

Click on ‘Terminal’

Type:
kextstat | grep prolific
and:
ioreg -c IOSerialBSDClient | grep usb
Your results should be very close to this:

Method 2:
Click on ‘System Preferences’

Click on ‘Network’

Now click on the ‘+’ sign on the bottom left, and then on the ‘Select the interface and enter a name for the new Service’ click on ‘Interface’ – you should be seeing the ‘USB-Serial Controller D’ there.

This will create a “Network” interface for a modem or serial port. Because it’s a serial port, it’ll say “Not Configured” and that’s normal:

From the “Advanced” button you can change default settings (usually not needed). And this won’t change the “Not Configured” message – that’s still ok.

Now finally, you need an application which will talk to the serial port. On Mac, the file which maps to the port is /dev/cu.usbserial. If you have a null modem cable and a terminal program on the other side, the Mac actually has a built-in terminal program called “screen” that you can use to test the connection.

Once that is up and connected (and if the serial ports are set to the same baud rate and paramters), you can type on either side and see the characters come across.

DisplayLink has released an updated Mac driver (1.7 beta 1) with support for Mac OX 10.7 “Lion” (both 32 and 64 bit kernels).

The driver is available for download now at http://displaylink.com/support/mac_downloads.php and is compatible with all Plugable USB graphics adapters and docking stations, such as the Plugable UGA-2K-A.

DisplayLink’s release coincided with Apple’s announcement today at WWDC that the Lion update will be available for purchase next month for $29. Driver updates from DisplayLink are free.

This new line of DisplayLink drivers (1.7 and later) is critical for all DisplayLink Mac users looking to upgrade to Lion, as the new OS release breaks all older USB graphics drivers.

The new DisplayLink driver release includes other fixes, but retains the same high-level characteristics and limitations of prior Mac driver versions (displays up to 2048×1152 on high-end USB adapters; limit of 4 additional displays via 4 USB adapters; no Quartz Extreme/OpenGL support).

You can attach up to 4 additional displays on any Intel Mac OS X system with DisplayLink-based USB virtual graphics adapters. Whenever images are redrawn, the CPU is heavily involved, so it may not be as snappy as your main monitor — but it’s the easiest way to build an amazing, plug and play multiple monitor setup on the Mac.

If you’ve never installed DisplayLink’s Mac drivers, here’s a walk-through of the steps (using OS X 10.6.7 and DisplayLink’s v1.6 Mac driver):

1. Fire up Safari, go to this page to download the Mac driver :
http://www.displaylink.com/support/mac_downloads.php

You’ll want to download the latest driver, because DisplayLink’s Mac drivers are still improving, and because new Apple OS updates often require updated drivers from 3rd parties.

2. Once there, make sure you tick the ‘I agree to the terms of the DisplayLink End User License Agreement (EULA)’ and then click on ‘Download Driver’.

3. Safari will instantly start downloading the driver and automatically mount it on your desktop. Once the download is done you should see a ‘DisplayLink installer’ icon on your desktop. Double click on the ‘DisplayLink Installer’ on your Desktop.

4. The ‘DisplayLink Installer’ will pop up. Double click on ‘DisplayLink Software Installer.pkg’

5. You may get a warning: “This package will run a program to determine if the software can be installed”. Click ‘Continue’.

6. On the ‘Install DisplayLink Software’ window click ‘Continue’ to proceed.

7. The ‘Software License Agreement’ will be presented. Proceed by clicking ‘Continue’ again.

8. Click ‘Agree’ to agree with the software license agreement.

9. You’ll get the ‘Select a Destination’ screen. Click on the disk where you want to install the DisplayLink Software, and click ‘Continue’ to proceed.

10. Install to the standard location – just click ‘Install’.

11. You should get a pop up for your password to alow the installer to make changes. Type in your password and click ‘OK’.

12. You’ll get a warning that the computer will need to restart. This is normal, click ‘Continue Installation’.

13. The installation will finish. You should get a message that ‘The installation was successful’. Click ‘Restart’ to finish installing.

14. When the computer finishes restarting, log in and plug in the USB-VGA-165. As soon as you plug it in, the secondary monitor should be autodetected and ready for use.

15. To further configure your monitors, do the following: Click on ‘System Preferences’->

Under ‘Hardware’ click on ‘Displays’

Click on ‘Arrangement’ to re-arrange your displays.

Finally to change your primary monitor, all you have to do is go to ‘Arrangement’. Click on the white bar and drag it to the other screen. As soon as you release the mouse the primary monitor will change.

Notes:

• DisplayLink’s virtual USB graphics don’t support OpenGL or Quartz Extreme, so apps that do high-end 3D or video should stay on your main monitor.
• DisplayLink adapters can support VGA, DVI, and HDMI as outputs (below is a high end one that supports all three, and a less expensive one that’s VGA only). They don’t support DisplayPort or any of the earlier Apple proprietary connectors, so watch out with Apple Cinema displays.

We’re really excited about this product. It has a clean, simple design. Power-sipping, so it can be powered by a standard USB 2.0 connection alone. Because it’s “just” a collection of USB 2.0 devices, it’s enormously flexible. And because of the simplicity, we’ve been able to hit the $64.95 price point, available now with next day shipping on Amazon.

The most common uses for a USB dock like the DC-125 are:

• You have a laptop, but would like to use it “like a desktop” when you’re at your desk. The DC-125 gives you quick dock/undock with a single USB cable driving an extra full-sized monitor (driven by DispayLink DL-125 chip, capable up to 1280×1024 / 1440×900), speakers, keyboard, and mouse already on your desk. The extra monitor can either mirror or extend what’s on your laptop screen.
• You want to save time, money, and power by leveraging one PC to support many users. The DC-125 is supported out of the box by Userful’s Multiseat Linux 2011™ and with available drivers on Windows Multipoint Server 2011™

If you’ve never heard of Userful or WMS2011, take a look at those links. Both require a software license (not included with the DC-125). But it’s amazing what’s possible with the enormous processing power of today’s PCs and the flexible and simple connectivity of USB 2.0 devices like this. It’s possible to realize huge cost savings with a similarly large power/environmental savings.

But most of our users will probably start with the simple benefits of laptop docking via USB. So here’s a video for a quick walkthrough of what the DC-125 offers in terms of functions:

We’re filling out our line of DisplayLink USB graphics adapters with two new products that offer even better pricing, using DisplayLink’s most cost-effective mid-range DL-165 chip.

1) Our new UGA-165 completes our USB to VGA/DVI/HDMI family. There are all identical products other than the DisplayLink chip inside the unit: UGA-2K-A (DL-195 chip), UGA-165 (DL-165 chip), and UGA-125 (DL-125 chip).

2) Our new USB-VGA-165 is our most aggressively priced product, hitting the new price point of $44.95, while still being built on DisplayLink’s mid-range DL-165 chip. We pushed the price point down by supporting VGA connections only (no DVI or HDMI, and no extra converters needed in the box), and with simpler casing and packaging.

Now with this complete line, we’re covering the full line of DisplayLink chips, with options from $45-$65. And we hope to add a higher end option focused on HDMI in the coming months.

If you’re a current owner of one of our other DisplayLink products, you’re going to like these new adapters — same drivers, same performance, same simple setup experience, and new lower price points for connecting even more monitors to your PC!

Here’s a table with more detail to compare the four adapters head-to-head.

So we’re excited to launch a hub with a lots of expandability (10 ports), but with a simple and clean design.

• Full USB 2.0/1.1 performance and compatibility. No compromises. Works on all platforms with no drivers (i.e. it’s a standard USB 2.0 hub)
• Cascaded Terminus Technology chipsets – the best designed, lowest power, most reliable USB 2.0 hub controller out there right now
• The 10 ports (plus upstream port to PC and AC power) are all on just two sides of the hub, minimizing cable clutter
• Two of the ports swivel to a vertical position – so if you want a flash drive or antenna to stick up, that works. If you want everything to lay flat so you can stack on the hub, no problem
• A blue LED bar down the center of the device signals power. 2.5A AC adapter included

The customer feedback from this hub design has been surprising us – you wouldn’t think in 2010 that a USB 2.0 hub could get people excited. But buyers have written with disproportionately positive feedback like “Easy to use and a really helpful device” and “Exactly what I was looking for”.

With many laptops only having 2 or 3 USB ports, the easy expandability of a hub like this is a nice win.

But compatibility with the Mac has been hit-and-miss. Mac OS has no special support for USB graphics – so DisplayLink’s drivers have to do quite a bit of work to integrate with the OS. And Apple’s new OS updates and platforms have sometimes broken the drivers, requiring another update from DisplayLink to set things right.

In particular, in the 15″ and 17″ MacBook Pro models introduced in 2010, Apple added hybrid switching Intel/nVidia graphics for power management purposes. The OS switches between them depending on whether lower power (Intel) or higher 3D performance (nVidia GeForce GT 330M) is called for. Unfortunately, that switching conflicts with USB graphics in Mac OS X in significant ways that DisplayLink has been unable to solve. As a workaround, users with these MacBooks can turn off graphics switching in the control panel.

On the bright side, with the 13″ MacBook Pro, Apple moved entirely to using nVidia’s latest low-power chipset, the GeForce 320M, which both is 1) an all-in-one non-switching solution and 2) makes use of integrated memory, which is a good match for USB graphics. This MacBook Pro doesn’t have the compatibility problems of the 15″ and 17″ versions.

The new MacBook Air, announced today, now too is potentially a great match for USB graphics – a small and light notebook for travel, but with the ability to connect many devices and up to 4 independent displays (one USB graphics adapter per display), all via inexpensive USB 2.0 hubs to expand beyond the two built-in ports.

But what about compatibility?

Fortunately, Apple has announced that the new MacBook Air uses the same nVidia GeForce 320M graphics solution as the MacBook Pro 13″ model, so the compatibility story should be the same. Just make sure to use DisplayLink’s latest 1.6 beta 3 drivers or newer, for full 64-bit OS support and the latest fixes.

This is based solely on the specs for now – hopefully we’ll get a newly minted Macbook Air owner to post here with their experiences. And again, for Mac OS X these are beta drivers for now, so only somewhat adventurous users should jump in to experience any of this multi-monitor madness.

The main feature of the new beta are fixes for some problems experienced on resume from sleep.

In terms of our general recommendations for Macs and Plugable’s DisplayLink-based products, we still want to emphasize that all Mac drivers are of a beta/pre-release level of quality compared to the Windows products. They still 1) are incompatible with recent MacBook Pros with switching graphics 2) disable the USB ethernet interface on docking stations like our Plugable dock. 3) are too frequently broken or fixed by Apple’s OS X updates — Apple often seems to be changing driver interfaces in subtle ways that affect USB graphics.

We expect and hope that support from both DisplayLink and Apple will improve in time, and we’ll be able to recommend the combination without qualification. Until then, it’s good to see releases like this for incremental progress.

Plugable uses DisplayLink chips for USB graphics, and ASIX chips for USB Ethernet functionality. And we have both chips in devices like our Plugable USB 2.0 Universal Docking Station.

Unfortunately, on Mac OS X, there is a conflict between recent DisplayLink drivers 1.5+ and the Apple drivers (AppleUSBEthernet) for ASIX chips. The DisplayLink drivers appear to open other USB devices as part of enumeration. As a side effect, this causes USB ethernet devices to show as “disconnected” upon return from system boot or hibernate.

That’s in addition to other graphics and ethernet driver compatibility breaks that Apple’s recent OS X 10.6 updates have introduced, including breaking AppleUSBEthernet for non-Apple USB ethernet hardware.

Until these issues settle down and are fixed in the drivers from DisplayLink, ASIX, and Apple, here is a workaround for the current issues with the ethernet function of the Plugable Universal Docking Station:

Step 1 is to download and install ASIX drivers that are compatible with recent Mac OS X 10.6: http://plugable.com/wp-content/uploads/2010/04/AppleDefaultDriver_v2.1.5.zip

Step 2 is to copy the following script to a file (call it “install”), and run “sudo ./install”

#!/bin/bash
sudo echo "#!/bin/bash" > /usr/bin/plugable-eth-reset
sudo echo kextunload -b com.apple.driver.AppleUSBEthernet >> /usr/bin/plugable-eth-reset
sudo echo kextload -b com.apple.driver.AppleUSBEthernet >> /usr/bin/plugable-eth-reset
sudo chown root /usr/bin/plugable-eth-reset
sudo chmod o+x /usr/bin/plugable-eth-reset
sudo defaults write com.apple.loginwindow LoginHook /usr/bin/plugable-eth-reset

Now, logging out and logging back in will automatically reload the ethernet driver. Unfortunately, this does not cover the return from low-power cases. Unless we find an improvement to the workaround, you’ll have to log out/log in or just run “sudo /usr/bin/eth-reset” so trigger the script.

As there may be variations in systems out there, please comment if you get different results, and we’ll post an update here at Plugable if (as we hope) this is fixed more directly in the DisplayLink or ASIX drivers in the future.

And, generally if you’re a Mac OS X user, please be cautious about OS updates which might break 3rd party hardware drivers. If you have non-Apple USB hardware, consider deferring updates until there’s time for other people to report on forums about compatibility.
