impossible to connect usb hardrive and mouse
 

I guys,

I have a problem with a vista home premium, when i connect my usb mouse or
my usb harddrive, the vista tell me i can install the good drivers??
In past when i plug the mouse it's work.
if i check the mouse and hardrive in another computer it's work well, and
windows install the good driver;

If someone have an idea ??

Thankx
