Yes.  It was at 100% when I checked that afternoon.

2.0.3 was the current version when I installed it.  For a while I
struggled with newhidups, but I never got it working properly.  Right
now I don't recall the problem, but it was discussed on the list.
Then I spent a while trying to solve the problem of the ownership of
the /dev/hiddev* files getting reset after a reboot.  I didn't quite
fix that either.  Then other things came up and I lost interest.  It
seemed to be working more or less OK.

I will probably get back into these issues soon because we just got a
new computer with a new UPS (an APC Smart-UPS).  Since this has both a
serial port and a USB, I wonder whether it will be less painful to stick
with the serial interface.
