I have a Win7 64bit Dell laptop on a domain and the notify bubble "USB device not recognized..." is aggravatingly annoyingly every second popping up. A friend had plugged in their usb phone but the issue starting a few days afterwards. The laptop is on a dock 90% of the time and I only have 2 monitors, a wired keyboard and a non receiver mouse plugged it.

1. Opening up device manager, the window jumps up and down.
2. When I can finally click on the root hub with the yellow exclamation to delete it, the issue will go away,...until a reboot.
3. chkdsk and scannow didn't resolve it either or turn up idea errors.

4. Turned off, unplugged, and removed the battery for a minute or two. put it back together and still no luck.

I'm ready to drop kick this laptop!!!!! Please Help
