[Boot loader] debug syslog menu doesn't list 16GB FAT32 USB thumb

[diver]

I can mount it once Haiku is fully booted but I can't see it in "Save syslog from previous session" menu.

fdisk -l /dev/sdb

The bootloader is fully dependent on the BIOS to enumerate and then write to devices. If it doesn't show up, there's really not a whole lot we can do about that.
