HP Prime wireless kit

Yes, the HID spec for USB is a very simple way to transfer information. Not to be picky, but the advantage isn't the absence of drivers, but rather that every device is certain to have one, right? That also sorta explains the 'MOUSE' function on the Prime: probably refers to the USB interface, not that a mouse might be attached to a calculator! (or could be the touch screen, IDK)

In any case the HID spec has an open API and barring some tricky stuff in the Prime code, should permit some clever use of the USB port. A bluetooth mouse works because it uses the same HID protocol as a wired one. Hmmmm . . .?
