Dell optical mouse disconnects then reconnects multiple times per minute. PC is unusable with this issue.
Windows 7 64 bit SP1, latest bios, latest USB drivers from my mobo manufacturer. Mouse works fine with other PCs.
Tried USB power setting fixes mentioned in Google search results. Tried disconnecting all USB peripherals (Microsoft Xbox controller, Logitech wireless keyboard, QuickCam, external drive).
Here's my Device Manager. There are two entries for HID-compliant mouse. Tried disabling / uninstalling but the pair comes back after a reboot. Also tried uninstalling everything under Human Interface Devices and both USB Root Hub entries. Help!
