Supporting PXE over USB Deployment Scenarios for tablets and ultrabooks

Many enterprise IT admins are facing a new challenge: how to deploy and manage systems with only WiFi for networking and USB for IO ports.  As a result, we’re often asked whether our USB network adapters support PXE boot.  In short, this is the wrong question- Mu.

When designing a deployment environment where USB is your fastest or only I/O option, it is likely that using bootable USB storage devices to abstract away from the limitations of the motherboard UEFI/BIOS will be your best option for two reasons:

1. Support for booting USB mass storage class devices is class-based and ubiquitous.  Almost all modern motherboard BIOS/UEFI builds support USB mass storage class device boot. A number of minimal OS with support for accessing a network share and installing the OS via this pre-installation environment. One valid option would be to use an CD ISO to USB bootable converter program like LiLi to create a USB Bootable iPXE environment, and add the open-source 88179 driver here if you need wired and can’t boot from built-in wireless. Another would be to use Windows PE with Bootcamp drivers for Windows as discussed here on Technet forums. In either case, the key is to build support for the network driver into a USB bootable pre-installation environment.

2. Support for USB network devices is not class driver based- individual chips have notable functional differences, and as such there is no class driver for USB networking- thus, support is left to motherboard OEM’s to build support for individual networking devices into their devices- a challenging task.

For this to be possible, the BIOS/UEFI on the motherboard has to natively support the chip used in the USB network adapter- so this answer will always depend on the motherboard, and require research into both the chipset of the USB network device and then whether the UEFI/BIOS a given motherboard runs supports this chip.

The vast majority of “legacy” systems will NOT have the ability to PXE boot a USB attached adapter. On more modern systems, this functionality will vary from model to model and is NOT something we can answer with certainty, as it is effectively a question of whether the motherboard’s software has support for the chip used in the adapter.

This is much less likely to work on newer USB 3.0 networking devices than on  USB 2.0 devices, since those are based on chips that have been around longer, thus giving motherboard OEMs and the open source community time to integrate support for these USB devices into BIOS/UEFI and the alternate pre-installation environments. 

Our most widely compatible adapter, capable of 10/100 operation rather than gigabit speeds, is the AX88772 based Plugable USB 2.0 to 10/100 Fast Ethernet LAN Wired Network Adapter for Macbook, Chromebook, Windows 8 and Earlier, Surface Pro, Wii, Wii U, Linux, and Specific Android Tablets (ASIX AX88772 chipset)

For Gigabit connection speeds (although potentially lower performance than the USB3-E1000), check for support for the ASIX 88178 chip used in our, consider the Plugable USB 2.0 to 10/100/1000 Gigabit Ethernet LAN Wired Network Adapter for Windows, Mac, Chromebook, Linux, and Specific Android Tablets (ASIX AX88178 Chipset)

While it is theoretically possible to select only hardware that has native support for booting form USB network adapters, unless you need to PXE boot regularly or are trying to integrate ultra books with SCCM or some other enterprise management system, in most deployment only scenarios it should be easier to use USB media to deploy from since it is relatively easy to setup a USB bootable pre-installation environment, and build support for the driver into the PE instead of having to investigate BIOS/UEFI support for USB network device chips before making every device purchase. Information about what chips are supported this way is virtually impossible to find outside of hands on testing.

Before You Upgrade To Mac OS X 10.9 (“Mavericks”)

Good news: Mac OS X 10.9 is available today and for the first time, it’s a free update, so app and hardware developers will be able to start counting on Mac hardware running the latest software in general (kinda like the iOS world).

Bad News: Mac OS X versions have historically broken some percentage of 3rd party hardware, and OS X 10.9 appears to have a particularly big impact. Many hardware devices will need updated drivers for 10.9, either because the older drivers simply don’t work at all, or because they work but with new problems.

If you can, it may be better to wait for the adventurous to forge ahead and report their findings on 10.9, before taking the upgrade.

DisplayLink Based USB Products

Users with DisplayLink-based USB Docking Stations and Graphics Adapters should avoid updating to 10.9, if at all possible. See here for details.

DisplayLink-based USB devices that work well on 10.8.5 (up to 4 additional USB displays) will be broken for most uses by the 10.9 update. In particular, 2+ USB displays or any HDMI-attached displays (even non-DisplayLink) don’t work reliably because of screen configuration issues.

We don’t know when this is going to be fixed — but evidence is it will require fixes both from Apple and DisplayLink, so that will take a significant amount of time.

If you are able to stay on 10.8.5, or if you only need a single USB attached DVI/VGA monitor on 10.9, use
DisplayLink’s latest 2.1 Beta drivers.

USB Network Adapters


Mac OS X 10.9 (and 10.8.5) includes support for both the AX88772 chipset and the AX88178 chipsets in our USB 2.0 USB Ethernet adapters, and UD-160-A docking station. For these chips, we recommend first uninstalling any ASIX drivers and repairing disk permissions before upgrade to 10.9 (relying on your built-in net connection), and just plugging in to use the Apple drivers after upgrade.


For our USB 3.0 Gigabit Ethernet adapter, an updated ASIX driver is required. In addition to Mavericks support, compatibility issues with Android File Transfer seem to be resolved. That said, we’re seeing reports of some new problems with 10.9 and would recommend caution. For those who have already updated to 10.9, the compatible driver is available at:
the latest ASIX driver version to get 10.9 compatibility. Note that this driver does not yet have the new 10.9 signature, so you’ll also need to click ok on installing the driver unsigned.

USB Serial Adapter

The latest driver version is required to work with 10.9.

Plugable USB to RS-232 DB9 Serial Adapter

Serial devices will be automatically created (“ls /dev | grep serial”" to see them), however the network control panel in 10.9 now no longer shows serial devices as connected, even when they’re in use.

Other Devices

For all of our other devices, we’re recommending in-box drivers, or they don’t require 3rd party driver installs (hubs, cables, etc).

If you have a question about a product we didn’t mention, please feel free to comment below. We’ll get it added.

And if you hit any 10.9 upgrade problems with Plugable products, we’ll work to help. Just email support@plugable.com anytime.

Plugable USB Ethernet Adapters – Driver Updates with Windows 8.1 Upgrade

Q: What actions are needed for installing Plugable USB Ethernet adapters when upgrading to Windows 8.1 from Windows 8?

Note: these instructions only apply to traditional Intel/AMD based Windows, not Windows RT

A: When upgrading from Windows 8 to Windows 8.1, if you have our USB2-E100, it is supported with no additional actions needed as Windows 8.1 has the driver built-in. This also applies if you have our UD-160-A USB 2.0 Universal Docking Station.

For our USB2-E1000 or USB3-E1000, you will want to be connected to the Internet to allow the Microsoft Windows Update program to automatically install the latest driver for both of our gigabit network adapters. We strongly recommend when upgrading to Windows 8.1 to select the option “Go online to install updates now (recommended)” at the beginning of the upgrade process.

For a clean install of 8.1 without upgrading, a preexisting Internet connection will be needed for Windows Update to automatically install our USB2-E1000 or USB3-E1000.

Also, while the Windows Update drivers function without any issues, we recommend downloading the latest drivers from ASIX for our USB3-E1000 for the best performance: Version 1.16.9.0
