Asking on linux-usb-devel@lists.sf.net would be a good start.  ;)

The linux/drivers/usb/ directory in Linux 2.4 has lots of drivers
that you can look at, including a usb-skeleton.c sample driver.

On that same mailing list, there was a very nice usbtest harness
posted just a day or 2 ago by David Brownell.
