Hi,
We are developing an HID multitouch device and we want to make it fully
compatible with Linux and Windows.
The device descriptor describes a mouse, keyboard and multitouch
digitizer as well as a set of features. When we have mouse or keyboard
descriptor along the touch device I can no longer get or set features.
It gives me a timeout error:
ioctl (GFEATURE): Connection timed out
This only happens in Linux.
I would like to know if this is normal, or if there is anyway of getting
more information about the parsing itself in order to understand the
problem.
Below is the device report descriptor
__ALIGN_BEGIN
static uint8_t HID_ReportDesc[]

I don't have much time to test it myself, but you can get a lot of
debug information via debugfs. Most distros enable it by default. Try
looking into /sys/kernel/debug/hid/<dev>/
These debugfs files contain runtime information about HID internals.

The only reason I can think of is that the driver at init used to call
GET_REPORT on all the input reports, and this is known to be broken on
many devices.
I added in v3.12 a quirk which is default for win 8 certified
multitouch devices: HID_QUIRK_NO_INIT_INPUT_REPORTS.
If you force your device to use this quirk, the behavior at connect
should be the same across all platforms, and hopefully, you will not
encounter this error anymore.
If you are running an older kernel, you can try using
HID_QUIRK_NO_INIT_REPORTS, but that means that the features will not
be called at plug (it all depend if you need to access the values of
these features at plug or not).
Cheers,
Benjamin
