I didn't change anything in /etc/default/grub but even if there is no
usbserial_pl2303.mod in core image it should work when the system was
booted.
The cable should be OK, I have test it before I upgrade the system.

After the upgrade from buster to bullseye I see the kernel output on
ttyS0 but there is no keyboard input available, neither in Grub.
Getty is startet on ttyS0, I see a login prompt.
Did anyone has had a similar problem?
Yourself, perhaps. Is this the machine that required
usbserial_pl2303.mod in Grub's core image? How did
you upgrade? Did you preserve /etc/default/grub or
has it been overwritten?
Cheers,
