This is not a bug in GRUB but simply your installation is wrong. Check your device map file.

GRUB will not boot from a USB floppy capable BIOS.
GRUB does not correctly handle USB floppy drives. The GRUB notification appears on the screen, but the system appears frozen. CTRL-ALT-DEL will still reset the system.

Dos 6.22, syslinux and lilo, all seem to handle the USB floppy fine. The BIOS (WizPro, I know sounds like fun)is set for legacy support.

I've traced the execution path through the assembly, but cannot understand why it seems to get where it gets if everything is ok.

The code appears to reach  jmp *(stage2_address), inserting copious debug messages, but falls on it's face.

Any help in debugging this?
