deleting (mouse) devices from Device Mgr ...?

Hi folks,

my mice have developed "hiccups".

i use both a PS2 and USB mouse (the ps2 is hooked up to a shared KB/ mouse /
monitor system that feeds 3 computers. never been a problem.) the USB is
one of those optical mice with scroll-wheel. nice.) using both mice on my
main XPpro box has never been an issue.

last couple of days, my mice are "hiccuping" - this means, usually after
engaging the mouse and clicking on a new item, the mouse pointer "jumps"
about 3 inches to the left on my screen. bit annoying.

thru the hardware panel, can I simply delete mice from the "Mice & Other
Pointing devices" list, and XP will re-build the drivers on re-boot, or with
automatic USB detection?

another similar question: can USB devices be deleted from the "Universal
Serial Bus Controllers" list (in device mgr) and they'll automatically be
re-installed? (i have both motherboard and pci-slot USB ports); my list has
4 "Intel 82801EB USB Universal Host Controllers, 1 Standard Enhanced PCI to
USB Host Controller, 2 USB Mass Storage Devices (might be the camera flash
cards I have plugged in), and 5 USB Root Hubs.

I'm sure a techie has talked me thru deleting some of these list items in
the past and re-boot auto re-builds them. Perhaps it was the ROOT HUBS
only.

any enlightenment on Mouse Hiccups and Deleting Devices from Dev Mgr would
be greatly appreciated.
