package grub-efi-amd64 2.04-1ubuntu44.2 failed to install/upgrade: »installiertes grub-efi-amd64-Skript des Paketes post-installation«-Unterprozess gab den Fehlerwert 1 zurück

After update at 06.08.2021 no USB Device could be connect, if Ubuntu is running from Hard-disk.
Running from DVD or starting BIOS USB is ok(Mouse, Keyboard),
While installing UBUNTU 20.04.2 from DVD no Problem, but after boot from Harddisk the connection to USB disappeared. Reinstalling GRUB connected USB till next reboot, but only by first try.
Sorry about my bad English, I am out of use.
