 * This file is part of the Berlios driver for WLAN USB devices based on the
 * Atmel AT76C503A/505/505A. See at76c503.h for details.
 *
 * This driver is derived from usb-skeleton.c
 *
 * This driver contains code specific to Atmel AT76C505 (USB wireless 802.11)
 * devices which use radio chips from RF Micro Devices (RFMD).  Almost
 * all of the actual driver is handled by the generic at76c503.c module, this
 * file mostly just deals with the initial probes and downloading the correct
 * firmware to the device before handing it off to at76c503.
