for the Linksys WUSB11 77b/2212 usb device, using the drivers at

http://at76c503a.berlios.de

last released version (0.11), compile, delete the usbvnet5 modules as indicated in doc, did a make install.

I used modprobe -v at76c503-rfmd
then plugged in my USB device, ran the iwconfig wlan0 stuff to get my wep etc. working, ran netcardconfig to get the dhcp stuff setup, and it just worked. Before installing these modules, I got hard lockups with this hardware. And this is on R4V4.1
