Wacom tablet

I have added a section to xorg.conf for the stylus. It now shows up in 
xsetwacom and works, but it's very intermittent.

When I use the stylus, it can take over 20 tries before the mouse cursor 
will actually move. When it does, it keeps working until I take the 
stylus away from the tablet, then usually won't work again for a while. 
It feels like the time it takes to start working again gets longer each 

I tried using cat on /dev/input/event0 and can see that I don't always 
get characters output when I use the stylus.

I have found out that if Xorg is connected, or cat is running, I do not 
get the disconnects occurring. Maybe that issue is only caused by not 
having an open connection to the device.

I have added the usb quirk, and it did get rid of the uhid messages. I 
only get the messages about ugen0.5 now (which I expect).

Thanks for your help.
