Details

I am using a KRAUN 300N router with relative USB wifi dongle:

http://yfrog.com/mtkraun300nj

The USB device uses staging driver rt2870; since when the linux-firmware was updated I can no more use it because it continuosly disconnects. I am using:

local/linux-firmware 20100623-2
kernel 2.6.35-rc4 (compiled from GIT sources)

I have also tried with the firmware file rt2870.bin downloaded from realtek site, nothing changes; hardware works perfectly under Windows (that makes me mad like a dog).

These are some of the dmesg lines related to the unusable hardware:

So which package do you want to report a bug against? You are using your own kernel when you experience the bug, not the Arch kernel.

hardware was broken, sorry for the noise. I have checked with other computers and OSes and the same problem happens.

The USB power pin must have a bad soldering
