at76c50x-usb ============ at76c50x-usb driver supports USB devices using Atmel at76c50x chipsets. Only 802.11b protocol is supported. The driver is using mac80211 stack. See also :doc:`at76_usb `, the driver which at76c50x-usb is based on. Status ------ The driver is working with some devices, but it hasn't been widely tested yet. Currently it's available only from `sky `__ wireless-testing tree. The maintainer of the driver is Kalle Valo . Send all patches to Kalle and CC linux-wireless mailing list. History ------- The original :doc:`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. Firmware -------- Some Atmel wireless cards require firmware to be loaded. The firmware can be downloaded from this site: http://www.thekelleys.org.uk/atmel/ Supported chipsets ------------------ - at76c503-i3861 - at76c503-i3863 - at76c503-rfmd - at76c503-rfmd-acc - at76c505-rfmd - at76c505-rfmd2958 - at76c505a-rfmd2958 - at76c505amx-rfmd TODO ---- * fix rssi values * short preamble support * short slot support * ad-hoc mode * debugfs interface to help debugging * power save * rts/cts * remove hex2str and mac2str * check frame sequence numbering
