Comment 1 for bug 522318

For the record, my HP 2710p (which worked (almost*) perfectly in Karmic) seems to be affected by this bug -- the pen is ignored in Lucid. This machine has a Wacom digitiser on ttyS0.

* (I say "almost" because Karmic treated the pen's right mouse button as a middle mouse button by default, which is presumably unrelated; I'll file another bug for that if it's still present when the digitiser is recognised again.)
