Sorry, cannot give you much support with USB problems of the Sourceforge
driver. I'm better with the alternative:
	http://at76c503a.berlios.de
This one also needs to have your USB ids added (in at76c503-rfmd.c)
Chances are that your USB problem doesn't show up, as the USB part of
both drivers differ a lot. If you still have it, please post the syslog
(with CONFIG_USB_DEBUG=y in your kernel config) and the "lsusb -v" of your
USB host controller.

No, normally the driver registers with the USB subsystem either for a set
of USB ids or it probe procedure gets called on every insertion of a USB device.

yes, AFAIR this is a kernel / modutils feature.
