ar9170 network interface initialization failure

ar9170 network interface initialization failure

[oshi]

Hello,

I am trying to enable a Ubiquity SR71 device on x86 - ubuntu 9.04 (kernel
headers 2.6.28-15).

I built and installed compat-wireless-2009-10-09 on my machine.
ar9170 module is loaded and a network interface is created.

However when I try to bring up the interface, an error occurs:

ifconfig wlan3 up
SIOCSIFFLAGS: Operation not permitted

I managed to trace down the error to  a failure in usb_submit_urb() called from
ar9170_init_mac().

The problem occurs also when using the single firmware file.
All the process was performed as root.

Am I missing any configuration phase?
Are there any usb patches i am missing?

Any suggestion will be appreciated.

Thanks,
Oshi

Hm, when usb_submit_urb err() fails on  ar9170_usb_exec_cmd() I
believe you should get a dump stack and all, not sure why you are only
getting this.

But the more important question is how you managed to compile
compat-wireless for ar9170 on a 2.6.28 kernel, we enable it on
compat-wireless only for kernels >= 2.6.29. Here is the config.mk
excerpt:

ifndef CONFIG_COMPAT_WIRELESS_28
CONFIG_AR9170_USB=m
CONFIG_AR9170_LEDS=y
endif

That is -- if you don't need 2.6.28 compat stuff enable ar9170. Also
2.6.28 does not have CONFIG_AR9170_USB.. hmm. How did you compile
this?
