Look at www.linux-usb.org
additional help with a USB ethernet adapter. The website does show the adapter as being supported.
Look at the output of the console command dmesg. Are there any messages relating to the device? Look at the output of the console command lsmod. What are the loaded USB modules?
I believe it uses the usbnet module and the device should be usb0
If everything appears to be loading correctly then try (as root):
ifconfig usb0 10.0.1.2 netmask 255.255.255.0 up
What are you trying to connect to? Do you need DHCP?
