Mouse scroll sometimes doesn't work

[®om]

Since today, my mouse scroll do whatsoever, sometimes it scrolls without doing anything, and if I scroll manually it doesn't... Sometimes during 1 minute it works again normally...

In /var/log/syslog, I have a lot of errors :

My mouse is :
Bus 002 Device 003: ID 046d:c025 Logitech, Inc. MX500 Optical Mouse

$ uname -a
Linux rom-desktop 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:57:59 UTC 2009 i686 GNU/Linux

In fact it seems there is a BIG delay between the moment when I click on the mouse and the moment when linux take it into account… Maybe 30 seconds or more…
Button1 and Button2 work correctly…

[This is an automated message. Apologies if it has reached you inappropriately.]

This bug was reported against the linux-meta package when it likely should have been reported against the linux package instead. We are automatically transitioning this to the linux kernel package so that the appropriate teams are notified and made aware of this issue.

If this bug really is a bug in the linux-meta package you can move it back to linux-meta and set the Status to Confirmed, or contact us on the #ubuntu-kernel channel on the FreeNode IRC server. Thanks.

Hardware problem.

Hardware problem ? I don't think so... It happens here too, exactly since yesterday : the last system update (Intrepid 8.10).
