Cnet 611 support

Just resubmitting this as I still need some guidance if anyone can help:

I got a little further thanks to Joerg. I compiled the kernel without 
USBDEVFS support (CONFIG_USB_DEVICEFS). Try again with debug also in
place and I get this:

Jan  8 23:43:59 mc kernel: hub.c: new USB device 00:10.0-1, assigned

It looks like it is finding the driver, then doing a usbdfu_probe then
exiting.. Still no success but maybe these messages give away what Im
not doing right.
