Hey everyone,
I’m running into issues with a HDMI/USB driven Touchscreen on a Raspberry PI3 when running it via Resin. The Display is working flawlessly however I can’t get the Touch Interface (connected via USB) to work.
The display is the following Waveshare 7" HDMI LCD C
I order to ensure the display itself is working I ran it with a bare Raspbian image and could use/interact the screen and its touch capabilities without any issues.
I started debugging the USB connection/device registration using lsusb and dmesg to notice the following:

Given that I had a though that the PI might not deliver enough power to the screen. However, I verified and max_usb_current is set to a value of 1.
Add this point I’m rather clueless how to proceed. I was about to blame it on a faulty display unit but was then reluctant after verifying that it works on a bare Raspbian install. Does anyone have any valuable pointers/insights or encountered similar situations? Any help would be highly appreciated!
Thank!
