The following patch (no backwards compatibility) allows ar5523 to work on kernel 2.6.25, while I've started to look into the API changes required for 2.6.26 that isn't finished yet. > If you're interested please remove all lists and only leave > linux-wireless on the reply. As long as ar5523 hasn't caught up with current wireless-testing HEAD, I'm going to work on an out of tree version available here http://svn.berlios.de/svnroot/repos/fullstory/ar5523/trunk/ svn://svn.berlios.de/fullstory/ar5523/trunk/ This contains only the *unchanged* driver files[1] required for ar5523, neither usb_probe.c (which only seems improve debugging), nor the required device firmware uath-ar5523.bin. For the time being I intend to keep necessary changes in a separate quilt patch queue, to retain the copyright information for each change and to allow basic bisecting. http://svn.berlios.de/svnroot/repos/fullstory/ar5523/trunk/debian/patches/ For now, all of my changes concentrate on making ar5523 compatible with current wireless-testing, I haven't started with actually debugging the driver yet. Unfortunately I cannot make any promises regarding the potential time scale of this porting, how far it'll get or if it will succeed at all, but I'd like to make a start and share the initial changes nevertheless. Hopefully this starts a broader effort to get this driver usable and eventually merged. As the question about which devices are covered by ar5523 has already been asked, I post the current annotated USB ID table for the driver[2] below. static struct usb_device_id ar5523_id_table[] = { AR5523_DEVICE_UG(0x168c, 0x0001), /* Atheros / AR5523 */ AR5523_DEVICE_UG(0x0cf3, 0x0001), /* Atheros2 / AR5523_1 */ AR5523_DEVICE_UG(0x0cf3, 0x0003), /* Atheros2 / AR5523_2 */ AR5523_DEVICE_UX(0x0cf3, 0x0005), /* Atheros2 / AR5523_3 */ AR5523_DEVICE_UG(0x0d8e, 0x7801), /* Conceptronic / AR5523_1 */ AR5523_DEVICE_UX(0x0d8e, 0x7811), /* Conceptronic / AR5523_2 */ AR5523_DEVICE_UX(0x2001, 0x3a00), /* Dlink / DWLAG132 */ AR5523_DEVICE_UG(0x2001, 0x3a02), /* Dlink / DWLG132 */ AR5523_DEVICE_UX(0x2001, 0x3a04), /* Dlink / DWLAG122 */ AR5523_DEVICE_UG(0x1690, 0x0712), /* Gigaset / AR5523 */ AR5523_DEVICE_UG(0x1690, 0x0710), /* Gigaset / SMCWUSBTG */ AR5523_DEVICE_UG(0x16ab, 0x7801), /* Globalsun / AR5523_1 */ AR5523_DEVICE_UX(0x16ab, 0x7811), /* Globalsun / AR5523_2 */ AR5523_DEVICE_UX(0x0846, 0x4300), /* Netgear / WG111U */ AR5523_DEVICE_UG(0x0846, 0x4250), /* Netgear / WG111T */ AR5523_DEVICE_UG(0x0846, 0x5f00), /* Netgear / WPN111 */ AR5523_DEVICE_UG(0x157e, 0x3006), /* Umedia / AR5523_1 */ AR5523_DEVICE_UX(0x157e, 0x3205), /* Umedia / AR5523_2 */ AR5523_DEVICE_UG(0x157e, 0x3006), /* Umedia / TEW444UBEU */ AR5523_DEVICE_UG(0x1435, 0x0826), /* Wistronneweb / AR5523_1 */ AR5523_DEVICE_UX(0x1435, 0x0828), /* Wistronneweb / AR5523_2 */ AR5523_DEVICE_UG(0x0cde, 0x0012), /* Zcom / AR5523 */ AR5523_DEVICE_UG(0x1385, 0x4250), /* Netgear3 / WG111T (2) */ { } }; MODULE_DEVICE_TABLE(usb, ar5523_id_table); ar5523 is also known as ar5005UG (802.11b/g) or ar5006UX (802.11a/b/g), as such the hardware[3] supports 54 MBit/s operations within the 2.4 GHz band (ar5006UX variants also in 5 GHz) and offers WPA support. Regards Stefan Lippers-Hollmann [1] Please ignore the initial Debian packaging under debian/, it just helps me with testing on obsolete kernels in order to forward port the driver.
