hi David,
I'm hoping you can point me in the right direction to get this working.
I have a USB device, which supposedly exposes an Ethernet Gadget
(RNDIS) interface.
The device is detected fine and works under Windows, but I just can't
get it detected on Linux.
The usbnet_probe() in usbnet.c doesn't even get called
