Windows 7 - I can't get to work Microsoft's Basic Optical Mouse v2.1 at Win7 x64

Hello guys,

This is my first thread on this forum so forgive for any kind of mistakes.
Well, Recenlty a friend of mine gave me a Microsoft Basic Optical Mouse v2.1 because mine broke and I was in need of another mouse.The first day I used it everything was ok but then Windows 7 started giving Unkown device message and errors.I can fix it but only temporary by plugging out the battery for 15 minutes after boot the pc the mouse will work but if the cable will be moved a bit,I will get unknown device message.
I would really appriecate any kind of help!
My System Specs
Acer Asprie 5738G
Intel Core 2 Duo T6400
Nvidia GeForce G105M
Windows 7 Ultimate x64
250GB HDD
Thanks,
Skouti

Sounds suspiciously like a damaged cable or a loose contact in the USB port. Try the mouse on a different USB port...see if that helps. If not then it's probably the cable itself...

Well, I think I didn't explain it so well.The mouse is a 100%working mouse but I can't get it to work on Windows 7 x64bit Machines to work,but I don't know why.
