USB mouse "jumpy" after suspend/resume - unless un/load uhci_hcd
Last modified: 2008-03-10 01:15:59 EDT
Description of problem: If i suspend/resume my laptop (dell latitude c600), the usb mouse is "jumpy" (slow refresh rate?) after wakeup. Integrated ps/2 touchpad and stick is still fine (note that ps/2 is affected by RH bug # 156418: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=156418 ) Version-Release number of selected component (if applicable): kernel-2.6.11-1.1287_FC4 How reproducible: Every time Steps to Reproduce: 1.Boot machine 2.(usb mouse fine) 3.suspend/resume (echo "3" > /proc/acpi/sleep) 4. usb mouse jumpy Actual results: Jumpy mouse after resume Expected results: Not jumpy mouse after resume Additional info: ACPI in general seems to work great on this laptop - no problems with it exept this thing. Note that if the mouse is plugged in before suspend/resume or not does not matter.
Just discovered - it works as normal if i unload/load uhci_hcd (rmmod and modprobe), it works perfectly again. Something get borked if i leave a USB mass storage unit mounted & plugged in while suspending - but i'll guess that is stuff for another bug report? I shall return with more data as soon as i find time to do some testing. There is some funkyness in the cd drive (it lets me eject it, even when mounted, once after a suspend - but that is also material for another bug. Seems like it get picked up, as the icon even disapears from my desktop. /me thougth it was a feature first :P).

If this bug has been fixed, but you are now experiencing a different problem, please file a separate bug for the new problem. Thank you.
There is no way that i can test this at the moment, as the system is broken. Sorry about being late for telling you.
Any progress with this?
Well, the machine is broken. If it is of high priority i can test it, but it has'n got a working display (external should work, tough)...
Ok. Shall we just close it (at least for the moment) as 'CANTFIX' then?
I don't know. I can see to it when i'm done with my exams (last one June 11th, quantum physics :) ), but before then, i don't got time. But is it just me who have seen this bug? But i can see the satisfaction of seeing this working properly...
Seems to just be your machine, sorry. I'll re-set the NEEDINFO so I don't get prodded :)
