[Q] How to get external wireless working? (LX CM11.0, USB OTG, ath9k_htc)

Hi all,

could someone please point me in the right direction to get my external wireless stick (TL-WN722N, htc_9271.fw) working on my Neo (haida)? My goal is to use my phone as a WiFi scanner.

So far I've done the following:

1) I downloaded LegacyXperia CM11.0 sources and configured the kernel to build the atheros wireless modules. The build of the LX ROM was successful and the ROM runs on my NEO.

2) I copied the atheros firmware (htc_9271.fw) to /system/etc/firmware

3) I insmodded the atheros kernel modules (ath.ko, ath9k_hw.ko, ath9k_common.ko, ath9k_htc.ko)

4) I installed and started Ubuntu Trusty via Linux Deploy

5) Then I connected the wireless dongle (TL-WN722N) to the phone with an powered USB OTG Y cable

6) I forced the usb configuration to overcome the 'insufficient available bus power' message in dmesg (sudo su -c 'echo -n 1 > /sys/bus/usb/devices/1-1/bConfigurationValue')

7) This triggered the firmware to get loaded, but unfortunately the device fails to get initialised, see the dmesg output below.

I would be happy about any help. Thanks heaps!
