I just happened to have a cheap USB3 that fails on attempt to boot when 
it is plugged into the USB2 port of my old laptop.

A variation is: not the same hub as keyboard and mouse.

So during some attempt installer picked existing ESP (expected). Does 
EFI/debian/grub.cfg on this partition contains valid UUID ("lsblk --fs" 
to list)?

Maybe I misunderstood your messages, but I decided that you could not 
boot from the installer USB stick any more. I suspected that Grub from 
installer tried to use config from some internal drive.

Does UEFI firmware settings (BIOS) allow to disable booting from 
specific drives? It took some time for me to discover this feature on my 
HP laptop (it does not allow to manage boot entries though).

A warning against excessively small ESP:
<https://fedoraproject.org/wiki/Changes/BiggerESP>

With the "windows" drive plugged in you still can create ESP manually on 
any drive and to specify its purpose.

I suggest to inspect output of

     findmnt /boot/efi
     efibootmgr -v

and to remove stale entries. If the ESP for Debian is on the Kingston 
drive then I suggest to remove EFI/debian from the Windows ESP. This 
directory might cause confusion later. (There is nothing bad to have ESP 
shared by multiple OSes, but it is less flexible in the approach with 
drive per OS.)
