tablet not working after pacman -Syu

Hi,

I recently did a pacman -Syu, and then after restarting my computer, X would not start, telling me that the driver for my tablet couldn't open the device. doing 'cat /proc/bus/input/devices' comes up with the following entry:

I: Bus=0003 Vendor=5543 Product=0005 Version=0100
N: Name="UC-LOGIC Tablet WP8060U"
P: Phys=usb-0000:00:0f.0-3/input0
S: Sysfs=/devices/pci0000:00/0000:00:0f.0/usb2/2-3/2-3:1.0/input/input1
U: Uniq=
H: Handlers=mouse1 event1 ts1
B: EV=f
B: KEY=c01 0 3f0001 0 0 0 0 0 0 0 0
B: REL=303
B: ABS=100000f

which is more or less the same as it was before the update. however /dev/input/event1 no longer exists, and trying to point the driver to the other two handlers comes up with the same error.

since the number after event changes from boot to boot, I had been using the following udev rule to make a symlink called /dev/tablet:

BUS=="usb", SYSFS{serial}=="0000:00:0f.0", KERNEL=="event*", NAME="%k", SYMLINK="tablet"

The tablet is a Genius MousePen 8x6, I'm using the wizardpen driver, which is in the aur (I am actually the maintainer.)

I'm not terribly knowledgeable about udev, which to me it sounds like is at the root of the problem, so I'm at a bit of a loss.

any help would be appreciated.

Re: tablet not working after pacman -Syu

I removed the 'NAME="%k"' from my udev rule and the device is now showing up, but I'm still getting the same error when I try to start X. I've considered the possibility that the driver simply isn't compatible with the latest version of xorg, but downgrading just the xorg-server package results in an xserver which won't start on account of not being able to use any of the drivers, so I'm having trouble verifying this. how do I go about figuring out exactly which other packages need to be downgraded to make the previous version of xorg-server work?
