Is it possible to run the G2H2 network over a USB-Ethernet adapter?
It is luck-of-the-draw on whether the driver in our kernel supports any given USB-Ethernet adapter or not. The adapters use one of many different controllers, and some might work while others do not. Even if you find one that works, you might not be able to get the exact module again because the vendor will change the internal controller. Because of this driver/controller issue, we don’t support the USB-Ethernet feature.
