Digitizer/Touch screen HID implementation from I2C

[ddB0515]

Hello all
Have some I2C touch digitizers and few touchscreens with embedded touch but all works over I2C and wanna try to make it working with tinyusb, already have written I2C communication to get touch position from touch IC (for now GT927(1) and ILI2511 with for multiple touches) so that part is done, now need to connect with tinyusb and make them as one

I have dumped one USB HID digitizer (from laptop that have USB touch controller) and exploring and learning how to make and work with USB descriptors so need a bit of help with getting that all in motion...

As I'm new to tinyusb and still learning tough would be good 1st to make discussion regarding it if someone already tried to make it
My assumption that I need to learn 1st a bit about HID and how tinyusb HID stack works then write Digitizer/Touch support to HID (something like hid_mouse_report_t) and make it working for multi-touch

Any guides/help/suggestion would be so nice and thanks in advance
