USB doesn't work sometimes

[theschnappster]

Hello, I have very strange problem
I have msi cr500 notebook, with Windows 7 64 bit with 3 USB ports. All of them were working properly, but now, one of them is making me troubles. When I plug in Bluetooth dongle, it doesn't work. When I plug in mobile phone it doesn't work. When I plug in another mobile phone it works. On 2 other USB ports every device works properly. I have drivers installed for every device, so that is not a problem.
Can you help me please? Thanks

Welcome!

It sounds like that one port may have a hardware problem. I encourage you to test it out thoroughly. Plug in every USB device you have to that port, and see which ones work and which ones don't.

If this turns out to be the case, you may be able to return it to the manufacturer if it is still under warranty.
