Yes, it is easy to make a userspace utility using libusb, or, probably,
hidapi. However, see below.

Um, which coordinate inversion problem? Could you please CC your replies to
Lana to DIGImend-devel, even though she can't send her messages there?

I doubt that Windows could affect that. The devices are supposed to be reset
on reboot, I think. However, this behavior is indeed strange. X.org logs for
both cases would help to understand the issue.

I don't think that it would help much without the kernel changes. My guess
is that the tablets would at least need a HID_QUIRK_MULTI_INPUT in
drivers/hid/usbhid/hid-quirks.c.

Still, M610 is not a KYE tablet. It's UC-Logic tablet. So, I don't think
the KYE tablet-enabling routine would help. But it maybe worth a try.

Unfortunately, I lost the ability to have an external IP for my home server,
so I can't give you a tarball link to the KYE-tailored usbhid-dump, but you
can checkout "kye" branch of
git://digimend.git.sourceforge.net/gitroot/digimend/usbhid-dump.git and run
"./bootstrap && ./configure && make dist" to produce one.

Sincerely,
Nick
