Hey there, hoping someone can help me get my touchscreen to work.
The screen itself is the SunFounder 10.1’’ Touch Screen, which plugs in via USB. The screen works fine on Raspbian.
From what I have been able to find, the chip is an Ilitek ili251x (ili2511QG010 to be exact).
Any help at all would be appreciated.
Hi @jayden,
Can you paste here the output of lsusb
with your touchscreen connected and without it connected?
This way we can see what driver would be needed for it to work.
Regards!

Thank you so much @spanceac,
The device shows up in lsusb
as the following, which isn’t very helpful.
Bus 001 Device 004: ID 222a:0001
So hopefully the results of lsusb -D /dev/bus/usb/001/004
are more helpful to you:

Hi @jayden,
This device seems to be supported by the hid-multitouch
kernel driver.
When you plug the touchscreen you should see with lsmod
that the driver is loaded.
A /dev/input/
entry should be created when you plug the device and your application should know how to parse the touchscreen data.
