I hope that is true and that I haven't been wasting effort on a faulty device.  I have tried with my printer's USB cable and seen the same thing.  I then tried it on my laptop (also on Fedora 32) with the same result.  To me this eliminates my PC and the cabling.

The correct file to edit is, of course, /etc/default/grub, and not /boot/grub2/grub.cfg
where there is no GRUB_CMDLINE_LINUX_DEFAULT.

However, the other suggestion of adding a file in /etc/modprobe.d/ is the better way
to add a module parameter without bothering with grub.
