Hello, I've got the same problem. I get this message a lot in dmesg: usb 2-2: reset low speed USB device using uhci_hcd and address 3

Another problem I have is: When pressing and releasing a key, the computer <http://forums.viaarena.com/messageview.aspx?catid=28&threadid=76926&enterthread=y#> does not realize the key release and therefore the key is repeated until I press a key again. That's very annoying. My keyboard is connected using PS/2. I know it's not USB, but I read that Gordon Messmer has the same problems, so maybe mentioning it may be useful. I am using kernel 2.6.21-rc3 with x86_64-mm-add-an-option-for-the-via-c7-which-sets-appropriate-l1-cache.patch. I am going to post usbmon outputs with a second email (after a reboot) Claas ------------------------------------------------------------------------- Take Surveys. Earn Cash.
