So I have this computer I built middlish of summer that so far has been great. It has this one quirk though that has been bugging me. Since the very beginning the mouse will occasionally not work once Windows boots. I'm using the same mouse and keyboard I've been using for the last two computers I've had which are both fairly generic USB devices. I've swapped in others, and even used one of those USB to PS2 adapters but still no luck. To get it to work, all I have to do is unplug it, and move it to a different USB port and it starts right up. About 3/5 times I boot up, the mouse works fine. The rest of the time it does this. The keyboard is almost always fine, but lately has started doing the same thing a little more often. I haven't booted into anything else that uses the mouse, but the keyboard works fine in BIOS, preboot, recovery console, etc. It is only at the login screen that things stop working.
At the suggestions of some others, I uninstalled the USB root hub and let Windows reinstall it, but nothing changed. It isn't a huge deal, but walking behind my computer and pulling plugs to get things to work is irritating.
Specs are:
Windows XP Pro SP2
Generic Logitech 2 button 1 wheel USB optical mouse
MSI K9N Neo-F AM2 NVIDIA nForce 550 MCP ATX AMD Motherboard
That should be all the pertinent hardware.
