Iv'e narrowed down a problem posted elsewhere to this. With my Pi 4 / 4GB my HP wireless mouse stops working when I plug in a SSD drive into one of the USB 3 ports.

Re: I can´t boot from usb in pi 4

I found this easy to follow guide on how to boot from SD then pass control to SSD / HD

Re: VGA <-> HDMI adapter with Raspbian

I think you need to comment out "hdmi_safe=1" Try booting the Pi with the HDMI lead disconnected, then plug in the HDMI lead (HDMI is supposedly hot pluggable) when the SD card activity LED has calmed down, and you may find you are getting the resolution you need. I eventually found that, in my case...

Sometimes it worked, sometimes a blank screen (actually 1184 x 624 but outside the monitors range). The voltage across the BAT54 was measuring >0.6v, board voltage 4.9V, leav...
