Hello all,
I am running the latest stock android OS on the VIM4.
Can someone point me to some documentation or lead me down the path of modifying a driver for a screen? Our client wants to use this screen and I can see the output through the HDMI, but there is no touch screen support through USB.
How hard would it be to add this?
Here is the screen:
@chandrian Problem with touch in Firmware V190816 - #17 by goenjoy
Adding USB touch support is simple. Just follow the steps mentioned in the above link to add the corresponding *. idc file.
I tried finding my device using “dumpsys input” but I am not seeing it:

Did you insert the corresponding USB device before executing the command?
I did and I didnt see it. I didnt see it on my windows pc either. I did see something under screens but not in USB
Any suggestions here?
@chandrian Maybe your USB touch device is broken, so first rule out whether your USB touch can be used?
Hi again,
I was testing and used the lsusb command and was able to see my device (Bus 001 Device 005: ID 16b4:0704) but when I use dumpsys input, I am not able to see it there. Any thoughts? Here is a dump:
