First of all:
It may be better to use a longer dd line and also to use the unofficial
firmware image available at https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/11.5.0+nonfree/amd64/iso-cd/firmware-11.5.0-amd64-netinst.iso
dd if=firmware-11.5.0-amd64-netinst.iso of=/dev/sdb bs=4M oflag=sync status=progress
That makes absolutely sure that the transfer is synced to ensure that it is
written to the stick and also gives you some idea of how well the transfer
is going.
Using the firmware .iso will potentially solve any problems with missing
firmwware.
The writing to a stick *should* work well.
All the very best, as ever,
