Hi LQ

I have been for one month a go with a problem that puled my hear for hours and couldn't find a solution to it, I made tons of Googling for that issue and with no luck at all, the seem problem return again and again randomly.

I have kernel 2.6.39-4 which is known as stable, a USB adapter with chipset rt3070. I succeded to compile and install both driver rt2800usb from one side and the rt5370sta from an other side. To run one of them I just blacklist the other one and then modprobe xxx ... yesterday I was able to browse the net with the rt2800usb normally, but suddenly after reboot when I plug the usb adapter I get a dirthy message saying :

[ 281.688657] phy0-> rt2x00usb_vendor_request: Error - Vendor Request 0x07 failed for offset 0x0580 with error -71

EDIT : dmesg I get also those errors :

The message is getting repeating in dmesg for many times, I didn't succeed to make the usb adapter work until now, always show me this error message, I tried switching to rt5370sta but no luck, tried to update the firmware and whatever I do I don't succeed at all, searched the net I have seen people setting hung_task_timeout_secs to 0, I did that reboot but nothing happing seem message always appear, I don't see anymore wlan0 or ra0 when tipping ifconfig, this command break many times as well and the system console refuse to respond when I plug the usb wireless so I was forced to open a new terminal tab ... really frustrating problem.



Any solution to that ? I don't think so but if someone knows please to tell me what should I do.

Hi there, why do you have to switch between those devices? And when you pull it are you unmounting the device first?
Can't both live together and just disable/enable one or other when you need with the command?:

Hi ukiuki

Thank you for the idea. The problem is so strange, when I reboot or startup the ubuntu box it fails one time but sometimes later it works !!! I can say that 80% fail and 20% succeed according to the number of times and rebooted and started up the system. Even with ifconfig wlan0 down or even even shutdown without unplug it it fails randomly! Even in a fresh install, and just now i have tried the new stable kernel 3.1.1 and it persists the seem error :
phy0-> rt2x00usb_vendor_request: Error - Vendor Request 0x07 failed for offset 0x0580 with error -71

After googling, there is the seem issue on lunchpad from 2009 and no defenite solution, even the problem itself is not clear, look here at :

Any help would be appreciated

Could you show us the output of lsusb?
