At work they disabled the possibility to turn off the screensaver. I use a
small program which "presses" every 59 second the shift-key. No extra
hardware needed. The program is called caffe1ne.
It works very well. The only problem is that when I'm making a selection in
excel (or every other program) the pressing of shift undo my selection.=20

You say that you want this device plugged in at all times, which
basically means that you want your screensaver off at all times, right?
So... why don't you deactivate it?

(This obviously doesn't resolve any USB problems you may have... :)
