A8N5X with an XP3700+ I have tried a couple of different drivers versions for\nthe motherboard, updated the bios, installed XP x64 and XP SP2, and STILL, my\nusb mouse stops responding for about 10-15 seconds at a time. It usually\nhappens when I have just opened or closed a program, and some programs will\ncause it to stop during use. (Mastercam, Firefox) A ps2 mouse works FINE, and\nif I have a USB keyboard plugged in, touching any key will instantly bring\nthe mouse back.\n\nShould I switch boards and see if that's the issue? It's about all that I\nhave left to try.... The thing is brand new, and I can send it back, I just\nwant to see if anyone has any ideas about this problem. The only thing I\nfound on google was someone saying that removing an ACPI device helped them,\nbut it did nothing for me.
