Hi;
I bought a new Offical Rpi Touchscreen display. Display is working good. But touchscreen is not working. It has FT5406 chip. I added it’s driver to kernel as module. When I want to add module to system with modprobe rpi-ft5406 then error : modprobe: can't load module rpi-ft5406 (kernel/drivers/input/touchscreen/rpi-ft5406.ko): Device or resource busy
What is the problem ?
