Hi, I recently got an old Wacom Intuos 2 tablet and am using it with a laptop (Lenovo W520, i7 processor) with Ubuntu 12.04 (64b). My xorg version is 1.11.3.

My tablet works fine when first plugged in, but if I unplug it and replug it, then it stops working and the only way to get it to start working again is by rebooting. More specifically, the lights on the tablet come on when I move the pen, but it isn't recognized as input--nothing changes on the screen.

I looked around online and saw a lot of cases where this wasn't solved or solved via hotplugging, but is that only applicable to earlier versions of xorg?

Sorry if there's an obvious fix here--I'm an ubuntu newbie and am pretty stuck.

Here's what I've tried:
--I've updated all the drivers--nothing's changed.
--modprobe does nothing.
--lsmod does show wacom:

I'm just stuck...do you have any suggestions?
Thanks so much!
