See some of the testing tips in the Linux-USB.org FAQ -

Some mice are USB 2 & some aren't. BIOS, USB controller, driver and
mouse polling speed can vary widely.

Check for BIOS updates & USB Hotplug configs in BIOS.

"system-config-mouse" is pretty buggy... it writes a best-guess mouse
config to /etc/sysconfig/mouse. You can edit this by hand & try some
other device and protocol options (cat /proc/bus/input/devices,
reconnect usb mouse & test again). Take a look at your
/etc/X11/xorg.conf & tell us what Driver and Protocol your using...
then, try the 'evdev' driver below in my xorg.conf Input Section
snippet. I use a MX500 mouse on a USB-PS/2 adapter for a KVM with this
config so comment out what doesn't work for you. -HTH Art

In your grub.conf at end of kernel line try...
kernel=psmouse.proto=exps
For XOrg 6.9 or greater, you'll want to use the new 'evdev' driver for
USB mice...
