Firmware for at76_usb Linux driver
==================================

The firmware is copyrighted by Atmel Corporation.  Please see file
COPYRIGHT.

Compatibility
-------------

The included firmware files are intended only for use with Linux
at76_usb driver for USB devices using at76c503, at76c505 and at76c505a
chipsets.  This firmware is not intended for any other OS or driver.

This package only includes only the firmware versions known to work best
with the current at76_usb driver.

Installation
------------

The firmware is loaded by the kernel using hotplug or udev.  Firmware
download is supported by udev starting with version 066.  If an older
version of udev is installed, then hotplug is likely responsible for the
firmware loading.

If you don't have either of udev or hotplug, please install either of
them, preferably using your distribution's facilities (yum, apt-get,
urpmi or a similar package manager).

Every supported device need just one firmware file, and the driver knows
which firmware to load based on the USB ID of the device.  But if you
don't know which firmware file your device needs, it's a safe bet to
install them all.

For the firmware to be found and loaded, it should be copied to a
directory where hotplug or udev can find it.

When udev is used, this directory is normally called /lib/firmware.  If
hotplug is handling the firmware, if would normally look in following
directories:

/lib/hotplug/firmware
  /usr/local/lib/hotplug/firmware
  /usr/lib/hotplug/firmware

For example, if you determine that the firmware is loaded from
/lib/firmware, copy the firmware files there as root:

cp *.bin /lib/firmware

The firmware download is initiated by the driver after it detects the
appropriate hardware.  No additional scripts or utilities are needed to
load the firmware.  See kernel log (using the dmesg command) to make
sure that the firmware download has succeeded.
