So, I ended up buying 4 power supply units. One had the USB C connector used on the Rasp PI 4. The other 3, two 3 amp and one 2.5 amp. , all performed the same. I even removed the bluetooth dongle for the keyboard and the HDMI monitor, again with no improvement.
Can you outline exactly what setup hardware wise you are using. My suggested setup would be
Raspberry Pi 3b or 3b+
Power supply 2.5ah or greater
CM19
Reliable Class 10 micro SD card 16gb or greater.
Nothing else attached to the USB ports.
Do you know how to image an SD card with the latest version of Raspbian Buster that will boot with WiFi enabled and SSH access.
For HG software setup if you want to send me a PM I can provide you with a simple list of copy/paste instructions. This setup will successfully load the CM19 driver. I tested the installation on Monday:
