Hi,
I have a raspberry pi 0 that attaches as:
cdce0 at uhub0 port 3 configuration 2 interface 0 "Linux 4.19.75+ with \
20980000.usb RNDIS/Ethernet Gadget" rev 2.00/4.19 addr 10
Unfortunately the cdce interface does not work with this particular device.
On the linux end, it turns out that cdc and rndis are being presented. When
NetChip is removed from the cdce driver, urndis(4) picks up the slack and
things work as expected! Linux also has the product id defined as RNDIS.
Debugged with patrick@ who is awesome and I now owe a beer or two for his
help! :D
OK?
Cheers,
Aaron
