Hi,
This patch (58e75155009cc800005629955d3482f36a1e0eec) is triggering a
regression with the following descriptor (report not working as
expected)
https://partner-android.googlesource.com/platform/cts/+/refs/heads/q-fs-release/tests/tests/hardware/res/raw/asus_gamepad_register.json
Didn't see anything obviously wrong with this gamepad descriptor, so
not sure what's trigger the regression.
Thanks a lot
Best regards

I'll have a look at it.
Do you have any more information on the regression? What exactly isn't working?

Added Benjamin to the mail thread.
For the record here's the report descritor, I have the feeling the issue is
related to the Usage Page being defined in the middle of the Usage

Well as it was stated in 57e75155009 ("HID: core: move Usage Page concatenation
to Main item"):
The spec is not pretty clear as 5.2.2.7 states "Any usage that follows
is interpreted as a Usage ID and concatenated with the Usage Page".
While 5.2.2.8 states "When the parser encounters a main item it
concatenates the last declared Usage Page with a Usage to form a
complete usage value." Being somewhat contradictory it was decided to
match Window's implementation, which follows 5.2.2.8.
This breaks the Report above as X, Y, Z and Rz will be concatenanted with the
'Simulation' Usage Page as opposed to the 'Desktop' one.
Based on the USB IDs can't find much information on this Gamepad, is it a real
one? If so I guess the solution would be to fix the report descriptor in a
custom driver. Otherwise I'd suggest fixing the descriptors directly on the
test suite.

And most of all, how does the joypad behave on Windows?
If no quirks is used in Windows, then maybe wee are not doing the
right thing, but AFAICT, the patch was added to mimic Windows :/
