at76c50x-usb driver supports USB devices using Atmel at76c50x chipsets. Only 802.11b protocol is supported. The driver is using mac80211 stack.
See also at76_usb, the driver which at76c50x-usb is based on.
The driver is working with some devices, but it hasn't been widely tested yet. Currently it's available only from wireless-testing tree.
The maintainer of the driver is Kalle Valo <firstname.lastname@example.org>. Send all patches to Kalle and CC linux-wireless mailing list.
The original at76_usb driver which had it's own 802.11 stack but based on the feedback in linux-wireless a mac80211 port was started and the driver was eventually renamed to at76c50x-usb. Help is very welcome to improve the driver.
Some Atmel wireless cards require firmware to be loaded. The firmware can be downloaded from this site:
- fix rssi values
- short preamble support
- short slot support
- ad-hoc mode
- debugfs interface to help debugging
- power save
- remove hex2str and mac2str
- check frame sequence numbering
