Subject: BUG: usb Mouse continual disconnect (2.6.22.10) leading to eventual crash?

Hi all,

I'm having a preblem with a few workstations that are hard freezing from
time to time since about a week.  Curiously since then we upgraded from
2.6.20.6 to 2.6.20.10...

While investigating I found out that there seems to be a problem,
occuring randomly on some workstations after a certain amount time, that
the mouse gets disconnected continously (see full log attached):

There are some occasionnal connect/disconnect due to the fact that we
recently bought an ergonomic mouse (Evoluent Vertical Mouse 3 Rev. 2)
that some people plug-in the workstation they are working for the
duration of their day/night shift... but nothing like 600 disconnect /
day / workstations?  And actually, the source workstation of this log as
not yet got the mouse connected to it since it's last reboot.

Looking at the changes between 2.6.20.6 and 2.6.20.10 I only found this
USB related:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.22.y.git;a=co
mmit;h=0e22438a5adfdf32b3bb1c75c81c01a29fba9770

I'm presuming that maybie eventually it might hit a input max barrier
(like a max of 1024) and then the kernel would be crashing?

Help very much appreciated!
