Hi
I appreciate that PCP/Jivelite works out of the box with the Pi's own
7in touchscreen, and the commercial reasons for doing that.

However, I am trying (as are others) to get PCP to work with the range
of Waveshare 5 & 7 inch touchscreens.  They are HDMI-attached for
video/audio and USB-attached for power and touch. This is good for PCP
of course, as it leaves the GPIO free for your favourite audio HAT of
course (although I use HDMI-audio, which seems pretty good to me).

Drivers etc., that work fine on Raspbian are all here:

These screens work well with PCP/Jivelite for HDMI video and HDMI audio.
However, although touch is working, it's so uncalibrated (touch
position not= cursor position) it's unusable.  

When trying to run this calibration command over SSH:

Code:
--------------------
    sudo TSLIB_FBDEVICE=/dev/fb0 TSLIB_TSDEVICE=/dev/input/event6 
/usr/local/bin/ts_calibrate
  
--------------------

...PCP enters the calibration process OK, but no longer responds to
touch at all during the calibration procedure, and just sits here:

...hence you can only crash out of the calibration process with ctrl-C
from SSH.

I have tried re-installing the Waveshare drivers from github (by adding
"git" command to TinyCoreLinux) but I'm getting out of my depth and not
achieving any progress  Any ideas?
