Multiple USB wireless devices? [Solved]

pootzko · 2010-08-24 18:21:24

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 (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

thank you

oh and yes, I downloaded needed ar9271.fw from linuxwireless.org and I put it into /lib/firmware
here's what dmesg outputs after inserting the stick:

on laptop

usb 1-5: ath9k_htc: Firmware - ar9271.fw not found
ath9k_hif_usb: probe of 1-5:1.0 failed with error -22

on computer where it works:

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

FYI ar9271.fw is in the linux-firmware package, which should be already installed, as kernel26 depends on it.

Or maybe you're using a custom kernel?

now that's interesting... I use the regular kernel and so I guess it was already there, but I didn't look before I downloaded the one from linuxwireless.org... and after I replaced it I made a mess... I just didn't assume it was there...

thank you for the info
