I have a broadcom wireless card in my laptop and as far as I know, it acts as an USB device. I also have one USB stick wireless device (TL-WN422G - uses ath9k_htc driver) which I want to use at the same time as the first (Broadcom) device.

The problem is, after I load ath9k_htc - iwconfig does not show the new USB device (the TL-WN422G - wlan1 / ath0 / whatever), but only the old one (wlan0 - Broadcom, checked by MAC).

I tried this USB device (TL-WN422G) on my other computer that has PCI wireless card in it, and they both worked just fine together after I pluged it in... I get wlan0 (Ralink) and wlan1 (TL-WN422G). Is it some kind of a problem for the laptop that both devices are recognized as USB? How do I make wlan1 appear on my laptop?

also, my system is fully up to date 2.6.35 kernel (Arch)

edit: I've already downloaded the needed ar9271.fw from linuxwireless.org and I put it into /lib/firmware - something wrong in that?

dmesg gives me this on laptop:

usb 1-5: new high speed USB device using ehci_hcd and address 9
usb 1-5: ath9k_htc: Firmware - ar9271.fw not found
ath9k_hif_usb: probe of 1-5:1.0 failed with error -22

and this on the computer that does work:

for some reason the ar9721.fw file was empty… downloaded the file again – put it into /lib/firmware and now it works…
