Ok guys I am having some troubles with my PC.

I have a USB Mikomi mouse (no driver for it available I believe).
I have 6 USB ports on my PC.

And all works OK. However everytime I connect any other USB device (Camera, Camcorder, Printer, Memory stick etc) my mouse stops working. The pointer just freezes on the screen. Nothing helps unless I switch of the other USB device and disconnect and plug back the mouse USB cable. It works OK after that.

As it happens with every USB port I am not sure what the problem is. Anyone has ideas?
