I have tried 2 different mice (a Logitech and a Microsoft) on my
laptop running Windows XP Pro SP3, and both of them were jerky. *I
finally traced the problem to the built-in ethernet adapter. *Once I
go into the Device Manager and disable the Intel Pro/1000 PL network
adapter, then the mouse will be smooth. *It will still be smooth even
if I subsequently re-enable the network adapter. *But if I restart
Windows with the network adapter enabled, then the mouse will be jerky
again.

Not sure what's going on here, maybe it's a resource issue. *I noticed
that the network adapter is on IRQ 16, and one of the USB Universal
Host Controllers is also on IRQ 16. *But Windows won't let me change
any of the resource settings for the mouse or the network adapter. *I
also tried a different USB port and still had the same problem.

Any idea on how to fix this?

If not, then is there a way to disable and enable devices from the
command line? *I'll just have a script disable and re-enable the
network adapter on startup.

What is the make and model of laptop? *Have you checked whether there is an
updated BIOS available? *Also, the manufacturers support site for any info
(in case there's a known issue)?

It is a Thinkpad T60. I did upgrade to the latest BIOS, and that did
not help. I have posted about this problem to forums.lenovo.com and
also forum.thinkpad.com, and no one seems to have heard of this
problem. A google search about this problem also really doesn't turn
up anything. It really does seem like a bizarre problem.
