Strange Mouse behavior

I am running Suse 12.1 64bit with two monitors on a Pentium with integrated graphics.

Since I got the computer every now and then mouse would start lagging behind the motion of the mouse.

It started getting a bit more frequent. Usually unplugging the mouse and plugging it back in would solve the issue. But not always.

I moved the computer the other day and now the mouse is always laggy. It wasn’t till today that I noticed how weird it actually is.

Nothing else happens on the screen while the mouse is lagging. Everything on the screen stops (movies, games, clocks, blinking cursors everything) while the mouse is lagging. As soon as the motion stops it all keeps going.
Restarting X, un plugging and moving to different port, and other mouses make no difference. Plugging it into a USB 1.1 or a USB 2.0 doesnt make a difference either. X is up to date as per 12.1-Update repo, as well as all drivers.

The Xorg log doesn’t throw any errors, it says the mouse driver is evdev but it also says evdev gets unloaded later. When I modprobe evdev, evdev doesnt show up in lsmod.
Dmesg doesn’t say anything that sticks out either.

Any help would be appreciated.

Have you looked carefully at the dmesg output? No, do not post the complete
thing, but look for potential problems with the USB system.

In addition, look at the results from ‘cat /proc/interrupts’. Does the rate
change dramatically when the laggy condition happens?

THANK YOU!

Get this, it was my TV tuner card. I put it in the computer while back but it never worked right. When I checked interrupts before and after moving the mouse there were a ton of new interrupts involving something called cx88. Then I rememberd my dmesg saying something about cx88 a bunch of times. When I googled it wikipedia said the that it was a linux module for controlling tv cards. So i pulled out the card and now the mouse works properly. It even fixed the issue I was having with my sound. Thank you so much
