It is using CO, not US.

Ah yes, sorry so you use this then:

country CO:
        (2402 - 2472 @ 40), (3, 27)
        (5170 - 5250 @ 20), (3, 17)
        (5250 - 5330 @ 20), (3, 23), DFS
        (5735 - 5835 @ 20), (3, 30)

So you loose out on 5490 - 5710 range given that the card has been
programmed for that regulatory domain. You cannot override this, this
built into the EEPROM and due to regulatory restrictions this cannot
be changed or left to the user to say where they are. On Linux we
however do enable the user to restrict the device further, but never
enable more than what the card was calibrated / designed for.

I am trying to debug this card since it works on kernel-2.6.36.2 but not
any later one.

Define "works" and "not works". You can bisect if you know two kernel
releases that you can use a bisection points, a good one and a bad
one. Please review how to do that.
