Subject: [PATCH for-5.19/uclogic v2 0/4] Add support for XP-PEN Deco L
Date: Thu, 19 May 2022 00:46:58 +0200 [thread overview]
Message-ID: <20220518224702.1409327-1-jose.exposito89@gmail.com> (raw)
Hello everyone,
This patchset adds support for the UGEE XP-PEN Deco L tablet.
This device belongs to a family of tablets that must receive a chunk of
magic data in order to be enabled (named UGEE v2 internally).
Once the device is enabled, its parameters can be discovered by parsing
a report descriptor. HUION v1 tablets have a similar report descriptor
but, in the case of UGEE v2 tablets, the number of buttons are also
discoverable [1].
The ability to discover the number of buttons is the reason for the
first 3 patches. They enable frame templates.
Because I lack the hardware to fully test this driver, I added some
KUnit tests to make sure no bugs are introduced.
I didn't see any other test in the subsystem (and I doubt I'm the first
person writing one) so please let me know if I need to move the test to
a different place.
The last patch enables the tablet and it should give Stefan a stable
code to work on his XP-PEN Deco Mini 7 tablet.
Stefan: I didn't include the code for the Mini 4 because once connected
no events are received until I unload and load the driver.
If anyone has a clue about why this could happen, I'd really appreciate
some help. [2]
Best wishes,
José Expósito
[1] I don't own a HUION v1 device, so I'm not sure if the information
about the number of buttons is also present and it is not used in
the driver for some reason.
