I've connected a GX Touch 50 to a Raspberry Pi via HDMI and USB. The screen works fine, however the Pi does not appear to detect the touch usb mouse.
Anyone tried this or have any ideas?

Hi,
Most likely impossible to fix, unless you are a linux kernel development or configuration expert: the touch is not on the usb; its embedded on one of the I2C signals inside the hdmi. And not done according to a standard way to put touch onto the hdmi cable.
USB on the GX touch is for power only.
If I were to go on this, Iโd start reading here:
https://github.com/victronenergy/linux/commits/sunxi_b4.19.119
And probably check the cerbo devicetree, as well as look for any commits that tweaked things to get them working.
But beware, Iโve no idea if we already have enough info public to get this working; and we canโt help in anyway with it.
Thanks for the info.
You could sell a lot of these with standard usb touch control.
Hi, I understand. But I'm afraid it is the way it is now. One reason to use I2C was probably that its lower cost.
