Sure. There must be a problem somewhere...

Okay, I've carefully read all of your tests, so let's recap:
- SGD (1.98x) cannot detect the USB drive (¿?)
- SGD (0.99x) can detect the USB drive
- GRUB is installed into the MBR of the USB disk
- The Partition where GRUB is stored is marked as booteable
I still don't know what is preventing the "true" GRUB (the installed one)
from booting but you can try to boot Debian directly with SDG (the
version that detects the disk, that is, v. 0.99x) and see what happens.
