[ltp] Datapoint: IBM ultranav USB external keyboard works "out of the box"

[Richard Neill]

Dear Paul,

Sorry for the slow reply - I had to actually find where I'd left my hub!
The answer is that when I unplug the keyboard from the usb socket, and 
replug it via a hub, everything continues to work just as before 
(including both trackpoint and pad).

I can't see any easy way to disable the touchpad in software - the whole 
thng appears as a single usbmouse as far as I can tell.

Trying to unplug the touchpad (by opening up the keyboard) *ought* to 
work in hardware, but it kills the trackpoint too! I can't see why - 
they have totally different connections to the pcb.


Best wishes

Richard
