Bug Description

using kernel 2.6.20-13-generic #2 SMP Sun Mar 25 00:21:25 UTC 2007 (FEISTY) and starting my computer with USB drivers conectec (MOUSE, Keyboard, Gamepad an printer) after I get to GDM my mouse stops working and my keyboard starts to act like mad.

if i run Dmesg with output the following error (it never stops until I rmmod uhci_hcd)
[ 1977.875052] usb 3-1: reset low speed USB device using uhci_hcd and address 2
[ 1977.875052] usb 3-1: reset low speed USB device using uhci_hcd and address 2
[ 1977.875052] usb 3-1: reset low speed USB device using uhci_hcd and address 2

To solve this problem I have to rmmod uhci_hcd unplug all USB devices, then modprobe uhci_hcd and reconect all the USB devices and after that it starts working normaly

Please attach (do not paste inline) the output of these commands (after you have rmmod/modprobe uhci_hcd):

dmesg > dmesg.txt
sudo lsb -v > lsusbv.txt

You might also try unplugging the gamepad and printer to see if it one of the causes.

It looks strange, but after I've done the steps above the error doens't repeat.

I can't replicate this error again, after I've done rmmod/modprobe uhci_hcd and unplug and then plug again the devices this error doens't appear again.

I've rebooted 3 times since then and the error doens't appear.

Strange...
