It's definitely a kernel issue. Hard-coding the serial numbers to a
fixed value let userspace work properly, so long as only a single tool
was in proximity at one time (the serial numbers are how individual
tools are distinguished).

So, in a nutshell: the wacom kernel driver doesn't always initialize the
device properly, and as a result it sends bogus tool serial numbers in
events to userspace.

I think this might simply be a race during device initialization, which
would explain why some people seem to see it and some don't.

the kernel driver.

Even unplugging the tablet and unloading wacom + usbhid + hid together
doesn't seem to reset whatever state is wrong.

When the tablet is non-working it is actually getting a serial of 0 for
every proximity event. This isn't fixed by unloading the wacom module
and unplugging the tablet, which leads me to believe that there's a
problem with the lower-level (USB?) driver stack.

I've confirmed that the kernel driver is actually seeing serial numbers
of 0 when the tablet isn't working, and large (magnitude) serial numbers
when it is by adding a printk to wacom_wac.c.

I've actually been able on occasion to get hotplug to work a second time
by removing and re-modprobing the kernel module, but success is
extremely rare.

I quickly looked at the Xorg.log files from launchpad below. Right after
hotplug of tablet, usbParse() goes in infinite loop and prints message about
invalid serial #. Not positive its infinite loop but at least the log stops
with no messages beyond repeating error message.
Upstream is saying this looks like a kernel bug, not an xorg bug.

Title:
Wacom Intuos2 tablet hotplug only works once after boot
However, except for the first time the tablet is plugged in, it doesn't
actually work. When using `xinput test`, no events actually seem to be
getting generated by the device.

Tried to use evtest on the tablet, but I'm not able to get evtest output
for either the tablet or the laptop's trackpad; I'm not sure what's up
with that. May be an evtest issue.
(Unlike the tablet, I do get output from `xinput test` for the
trackpad.)

Apparently evtest only works for pointer devices while X isn't running.
Anyway, with X turned off temporarily I can get useful output from it.
Apparently this is a kernel issue, and not an X issue, since I can
replicate the bug without X.
Steps to reproduce:

I think I'll file a separate bug since this appears to be similar to but
not the same as the issue originally described. (We do see the tablet
being plugged in in Xorg.log each time, the kernel driver just isn't
generating events anymore.)

`xinput list` even shows the expected:

It seems, actually, that udev and the xinput bits in the xorg server are
at least doing what they should. Subsequent plugs and unplugs are
reflected as they should be in udev:
