Hello everyone, I am new both to Linux and Backtrack so I apologise if I am missing something obvious regarding my problem. I am glad that there is a forum like this to help us =)

I am having trouble with the tl-wn722n wireless usb adapter. For some reason the device is labelled as unresponsive, as the log below shows:

(dmesg)
[ 280.332694] usb 2-4: USB disconnect, device number 3

My internal adapter is working fine:

And Tl-wn722n is correctly plugged:

I have backtrack installed on my pc, and I have tried with several versions (gnome, kde, 32 and 64 bit) although I know that this was futile perhaps, I also tried powering the computer with the adapter already in place, and other methods, like rebooting. I also tried reinstalling the latest drivers, although backtrack 5r3 was fully was fully up to date regarding the drivers.

I also know that the problem does not come from either the adapter or backtrack as I have tried it on another computer running backtrack.

Could the problem be from the usb port? The fact is that I only have one working usb port left in this computer, as the other ones are broken. If that's the case, do you think it is worth it to try installing windows and see if the device works?

I really appreciate your help in solving this issue, thank you.
