So I'm left wondering what's processing these device events and sending them on to the input subsystem, and, probably more to the point, where can I intercept them (in the kernel) so that I can do my affine transformation magic on x and y ? Is it actually all handled by hid-input.c ? It seems like me adding the rotation as a quirk would be an awful thing to do in such a generic place, and that I need to figure out how to force it to use hid-multitouch or maybe something new.WAVEPOS 6. I do not think that's being used here because there's no mention of it in dmesg or /sys.

Net, I looked in drivers/hid to see what sends those, and the only thing I can find is wacom_wac.c. I'm left trying to figure out how this works, and wondering if it's not being used as a multitouch device at all but, rather, it's just sending EV_ABS events. Getevent does see events from touches: /dev/input/event1: EV_SYN SYN_REPORT 00000000 Found special quirk 0x48 for HID device 0x0eef:0x0001īut I think I see evidence that it is being driven by only hid-generic: hid-generic 0003:0EEF:0001.0001: input,hidraw0: USB HID v2.10 Pointer on usb-0000:01:00.0-1.1/input0Īnd there's no code in hid-generic to deal specifically with touch screens. usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 1-1.1: New USB device found, idVendor=0eef, idProduct=0001, bcdDevice= 1.00 What I found is that function never gets called. Which I thought would mean it would use hid-multitouch.c as the specific hid driver, but I put debug messages in mt_touch_input_mapping() which is where I thought I would do the transformation. There is a quirk that match this vendor:device: hid-quirks.c: , I'm trying to track down where to do this. In Xorg I would fix this with calibration, but I'm trying to do something in android 11, so I need to take a different approach. The problem is that the X-Y orientation of the display is 90 degrees off from the touch controller. I have this Xenarc 7' touch screen with an eGalaxy controller, USB 0eef:0001.
