Sorry for the late reply. There is no specific driver for this adapter. You can try installing the chipset driver for Windows 8.x from our download site. There is also an ME Management Engine driver and Other Drivers USB to LAN that you can try as well. I’d start with the chipset driver and see if this helps.
Another thing to try is unplug the adapter, open Device Manager and plug it back in, it should show up as a device (it may be an unknown device); right click on the device and go to Properties. Go to the Details tab and under Properties click the down arrow and select Hardware IDs. Any of the values that come up, you can Google the value and see what comes up as far as driver information.
