4 years ago I temporary fixed it with adding a shell script which powers the usb off and on:
/home/pi/restart_usb.sh :
!/bin/sh
sleep 1 sudo uhubctl -l 1-1 -a 0 sleep 1 sudo uhubctl -l 1-1 -a 1
**/etc/xdg/lxsession/LXDE-pi/autostart:
@lxpanel --profile LXDE-pi @pcmanfm --desktop --profile LXDE-pi @xscreensaver -no-splash @point-rpi @unclutter -idle 0 @python3 /home/pi/myprogram.py @xset s noblank @xset s off @xset -dpms @sh /home/pi/restart_usb.sh
I see some errors:

Anybody got a better idea?
Hello, I have a 5 inch capacitive HDMI touch screen bought on eBay that is connected to a Raspberry Pi 4 of the first series.
The problem is that after rebooting the RPI (sudo reboot -h), the screen shows weird (not always, but most), but when I unplug the USB connector coming from the CTOUCH port and plug it in again, the screen displays the content correctly. The HDMI cable is plugged in at the first HDMI connector which is right from USB-C socket.
Raspian buster is running (5.4.51-v7l+ #1333 SMP). The RPI power supply is the original 3A. No other hardware is connected. I used LCD-5-show and played a lot with the parameters.
