Good day,
After much time and experimenting I have found a way to get the bootloader "boot device" choice prompt to come up on the screen reliably.
The USB-keyboard must be plugged into the upper USB 3.0 port on the Pi-5.
The USB Mouse must be plugged into the USB switcher. My switcher is USB 3.0. The prompt for boot device will come up whether the USB switcher is plugged into USB 3.0 or USB 2.0 on the Pi-5.
This works, but is not very convenient when needing to share keyboard and mouse between two or more computers.
It appears to be a Pi bootloader timing issue. Does anyone know of any variables in the bootloader process that can be adjusted to make this a more useful and reliable operation?
Thank you.
