Hello,
Greg K-H pointed me this way from linux-usb; I've had no replies there, but if
you've already seen the message on linux-usb, nothing's changed in the text
below or the attachments.
I'm trying to get a Zytronic single-touch touchscreen to work with Linux
kernel 3.5; it previously worked on a 3.0 kernel. I'm happy to try git kernels
and patches, even if they're just intended to gather more information.
hid-multitouch is picking up the device because it has multitouch report
descriptors as well as the single-touch descriptors. There's a quirk to make
it use MT_CLS_SERIAL, but that seems to be insufficient for my needs.
I've got as far as determining that it's mt_event in hid-multitouch.c that
consumes the events, but as the screen never sends the events hid-multitouch.c
expects to see, mt_event nevers sends an input event.
evtest on 3.0 shows touch events as expected. evtest on 3.5 shows no touch
events.
I've attached /sys/kernel/debug/hid/0003:14C8:0005.0001/rdesc as
zyntronic.rdesc and /sys/kernel/debug/hid/0003:14C8:0005.0001/events while I
touch the screen as zytronic.events.
I had evtest /dev/input/event5 running while I captured zytronic.events, and
got the following output:
Input driver version is 1.0.1
Input device ID: bus 0x3 vendor 0x14c8 product 0x5 version 0x101
Input device name: "Zytronic Displays Limited Zytronic Touchscreen Controller"

Any ideas, or instructions for gathering more debug information will be
gratefully received.

Hi Simon,
well, it's a known bug. This panel is now fixed in 3.6-rc0, and I
submitted the fix for stable. I'm still waiting for the stable
approval.
BTW, Zytronic 0005 is a multitouch device and not only a single touch
one. So I think we should handle it through hid-multitouch. I know
that Zytronic develops its own driver in parallel to fix some problems
they may have with the multitouch layer. This will also allow them to
flash their firmware.
Cheers,
Benjamin
PS: the fix is at
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=4aceed37e315e8eaa26cb4c8dfd619a32fa24669
