My computer will not recognize my Genius Mousepen 8x6...

it happens in two cases 1)first try to check out the device by connecting it in another usb port. 2)if it shows the same problem there then its the problem of the usb port internally,where the device wire is been connected. its actually by a screws internally.if the screws get loose the port becomes weak so the connection of the device does not get completely and properly detected.or the other case can be that the port internally is got loose change the usb port of the machine where you are connecting the machine.the new spare port is easily available at local computer shop. thanks.
