Comment 10 for bug 310095

Hello,
I stumbled upon this bug because I have problems with usb-2.0-devices too - a regression after installing the 2.6.28-13-generic kernel. We found out that for many the problem was the alsa-driver, more specific, the snd-hda-intel module. In some versions it breaks the usage of usb2. Has anyone experienced this too? Has anyone gone into this?
