Plugable USB 2.0 OTG Micro-B to 10/100 Ethernet Adapter


Plugable’s new USB 2.0 OTG Micro-B to 10/100 Network Adapter combines the compact external design and wide compatibility of our popular USB2-E100 adapter with a OTG Micro-B connector, making it the perfect choice for easy connection to tablets and smartphones that support the ASIX AX88772 chipset (see below for some compatible models). Its connector plugs directly into the micro USB ports found on many of those devices without the need for a separate OTG (on-the-go) cable. Although it can also be used on desktop computers and laptops with a standard USB port, this is not recommended, since it requires a Micro-USB female to Standard USB male adapter which is not included. We recommend our USB2-E100 for those applications.

Using this adapter to connect a compatible device directly to an Ethernet cable can result in speeds two or three times faster than WIFI. It is perfect for situations where WIFI is unavailable or unreliable, providing better video and movie streaming, downloads, and gaming.

Windows Compatibility

This USB2-OTGE100 adapter is compatible with all Windows 10 and 8.1 tablets with Micro-USB port.
On Windows 10 and 8.x tablets, the drivers are pre-installed.

Android compatibility

If the Android phone/tablet has the built-in driver of this Ethernet adapter, it starts working once plugged into the micro USB port.

Please Note: Android doesn’t have any external indication of connection through Ethernet. The only way to know for sure is to go into Airplane mode, then try to connect to the Internet. If you can connect, then the Ethernet connection is good.

The following Android devices have been tested or reported with the USB2-OTGE100. If the “Driver Support” column is “Yes”, this adapter may be able to work with the Android device:

Q. What do the green and amber LEDs on the Plugable USB2-OTGE100 indicate?
A. The green power LED on the Plugable USB2-OTGE100 is an indication that the Ethernet cable plugged into the adapter is live and it stays steady as long as the live cable is plugged in. The blinking amber link LED is an indications that data is transferring through the adapter.

Both these LEDs will not light up when:
1) The adapter is not receiving enough power because it is plugged into a port that does not provide the required 500mA of power
2) The drivers for the adapter have not installed properly or is corrupted
3) The plugged-in Ethernet Cable is not live or is faulty
4) The adapter has failed

Q. Are there any special considerations to make for Android devices with this adapter?
A. Nearly all Android devices will only be able to configure the adapter using automatic configuration (DHCP) and do not support manually setting IP address information. Some apps may refuse to connect through a wired connection, but most will allow connecting through the wired connection. Lastly, some Android devices may require being set to airplane mode in order to use the wired connection.

Q. Why does this adapter work with some Android devices, but not with others?
A. Basically Android doesn’t allow users to install any additional device drivers. Hence, if you wanted to connect an external device to an Android phone/tablet, the particular device driver has to be built into the phone/tablet when it’s shipped from the manufacturer.
Our USB2-OTGE100 Ethernet adapter is using the AX88772 chip set which is one of the most popular and widely adopted USB to Ethernet chip sets. A significant portion (but not all) of the Android devices available have the driver built in. This is why this adapter works with some of the Android devices. Unfortunately, there isn’t a good way to figure it out if the drive built-in or not, except via our collected data (the table above), or by testing the adapter with a particular Android tablet/phone.

Q. I feel this adapter is getting warm
This adapter runs of USB 5V bus power, and stays within USB 2.0 maximum of 500mA. The AX88772 converts USB 5V into lower voltage used over Ethernet. The excess voltage is dissipated as heat. Warmth to the touch is expected during normal use.

Q. Are there any known software conflicts?
A. For Mac users, there is a known conflict with the Android File Transfer Program.
