I've been trying to get that DUB-E100 with the asix AX8872 chip to work,
and didn't succeed.
Could you please share with this list how did you get it to work?
I've tried adding a new ProductID and VendorID to drivers/usb/net/asix.c
and use the ax88772_info driver_info struct. The kernel recognizes it as
the correct network card but when I perform a ethtool eth0 the only
output I get is:
Settings for eth0:
Current message level: 0x00000007 (7)
Link detected: yes
Can you give me a hint on this
