Touch Player on Samsung qb65h-tr

#1

Hi Folks did somebody know if the touch player works on th samsung qb65h-tr. I tried but i think i make something wrong. It is not touching??? Is there someone who use this screen??

#2

How is that screen connected to the Pi? Using USB I guess? Can you open a shell to that device and check if there’s anything happening if you touch the screen?

#3

The Screen is connected with HDMI and USB. When i open a shell and have a look wih the logread -f command i dont see anything.

#4

If you connect and disconnect USB, do you see added output if you run dmesg on the Pi? The screen should be registered as a HID (human interface device).

#5

Do you know in wich line this happend? I dont see anything!

I think I see something: usbcore: registered new interface driver usbhid.

These are the relevant log lines I could find running dmesg | grep USB:

[    1.149899] dwc_otg 3f980000.usb: new USB bus registered, assigned bus number 1

I don’t see any obvious input device? What happens if you unplug/plug in the USB cable to the display again? It should add additional log lines, so we might see how and if anything is detected by the Pi.

OK Now everthing works!!! Wrong USB Connection

Nice. I guess it would make sense to have some kind of device output mode for that package where you can see all the connected USB devices to make debugging these kind of issues easier…
