[solved] AR9271 chipset Wifi USB, Firmware not loading?

Hi,

I have this wifi adapter
https://www.olimex.com/Products/USB-Mod … R9271-ANT/

here is the output of "usb-devices"

T:  Bus=01 Lev=01 Prnt=01 Port=10 Cnt=01 Dev#= 19 Spd=480 MxCh= 0
D:  Ver= 2.00 Cls=ff(vend.) Sub=ff Prot=ff MxPS=64 #Cfgs=  1
P:  Vendor=0cf3 ProdID=9271 Rev=01.08
S:  Manufacturer=ATHEROS
S:  Product=USB2.0 WLAN
S:  SerialNumber=12345
C:  #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=500mA
I:  If#=0x0 Alt= 0 #EPs= 6 Cls=ff(vend.) Sub=00 Prot=00 Driver=ath9k_htc

here is the output of "dmesg"

[  379.417460] usb 1-11: ath9k_htc: USB layer deinitialized

[  631.363567] usb 1-11: ath9k_htc: USB layer deinitialized

I have tried with the htc_9271-1.4.0.fw and also firmware from here:
https://github.com/qca/open-ath9k-htc-firmware

both result in the same "failed to initialize" output in dmesg.

It does not show up with "ip link"

any help appreciated.

There's a bug in the current set of stable kernels with ath9k chipsets, see https://bbs.archlinux.org/viewtopic.php … 4#p1912134
