If a device presents itself as an HID game controller, it will work with the FRC Driver Station and its status will be communicated to the robot. A mouse or keyboard won't do anything useful for controlling the robot.

From the brief look I just took at the documentation, the Belkin N52TE actually appears as two joystick-like devices plus a keyboard and a mouse. The special driver software that comes with it lets you configure keyboard/mouse macros to correspond to its buttons, which isn't helpful for our purposes. I think it would take quite a bit of custom Windows driver programming to make it function in a way that would work with the Driver Station in a useful fashion.
