My computer is verging on usable due to this infuriating and consistent problem. For the last couple of weeks my mouse intermittently disconnects several times a minute. I have confirmed that it is a software, NOT hardware problem. I did this by testing the mouse in safe mode and on another computer, in both cases there was no issue whatsoever. Also the optic lase NEVER goes out so it isn't a short in the cord or USB head. Usually it reconnects on its own in anywhere from 1 - 5 seconds. But sometimes I get the "USB device unregonzied/failed" pop up in the system tray and I have to unplug and replug the mouse. Upon reconnection Windows plays the "bedoop" sound, as if a new device was just connected. One time, and only once, it happened to BOTH the mouse and my keyboard at the same moment. I suspect the problem is rooted in my system's USB drivers due to the symptoms described above. I have tried all of the following to no avail :
1) Uninstalled Mouse drivers and all related software before reinstalling.
2) Uninstalled hidden devices in HID and USB categories inside of "Device Manager".
3) Made sure the "allow computer to turn off device to save ower" box was unchecked in all of the USB root hubs within "Device Manager" (they already were).
4) Made sure "USB selective suspend" in "Power Options" was disabled (it was).
PLEASE help me out with this, I'm pulling my hair out over this!
