Bug#749709: general: USB mouse lag, while PS2 mouse is OK

[Nikolay Shindarov <phpshindaroff@gmail.com>]

Package: general
Severity: important

I am getting occasional mouse lags (like seconds-lasting freezes) when running
Debian Wheezy stable with default (Gnome 3 shell GUI). The mouse cursor just
stays on one place for a second and after that moves to where I have pointed
it. Same thing happened to scrolling a page with the middle mouse button - a
lag of around a second.
The problem is hard to reproduce and happen occasionaly. My mouse is wireless
and I even suspected the battery is to blame, however, after replacing it with
a fresh one the same thing happened.
Rplaced it with another USB mouse and after that with PS2 mouse. All USB mouses
seems to have the lag but the PS2 is OK. Even stranger, in xinput --list it
shows 2 mouses when I connect one USB mouse.
My PS2 mouse is old and not good and I am still looking for a way to get my USB
mouse working normaly.
