So the trick is to also have a USB 4GB drive plugged into the 4 port hub. At
just under 3 minutes (compared to 42 seconds for the Pi3) the little blue light
on the Transcend blinks and the menu bar shows up on the HDMI display and up
pops the little list of what removable drives are available.
Then, press the button on the USB switch to move the keyboard and mouse over to
the BBB and bingo! Mouse motion.
So this test version of the LXQT 2021 Debian Buster (as do pretty well all the
older versions) have an issue with throwing out the USB port if nothing was
found while booting.
This time we have:
starting USB...
USB0: scanning bus 0 for devices... 2 USB Device(s) found
scanning usb for storage devices... 1 Storage Device(s) found
Compared to before where there's only the 4 port USB 2.0 Hub:
starting USB...
USB0: scanning bus 0 for devices... 1 USB Device(s) found
scanning usb for storage devices... 0 Storage Device(s) found
Hopefully the reason for this will be easy to fix.
Meanwhile I can now get back to trying to get the CAN1 bus stuff running. I
have a fairly long document I'm putting together that explains how to get all
this working.
