I am not sure wether I am correct, but in fact I boot from my scsi disk. There
is a GRUB installed in the MBR. That GRUB boots the GRUB on the USB disk.

(part of) linux kernel configuration:
Device Drivers ---> USB support --->
<*> Support for Host-side USB
[*] USB verbose debug messages
[*] USB device file system
<*> EHCI HCD (USB 2.0) support
<M> OHCI HCD support
<*> UHCI HCD (most Intel and VIA) support
<*> USB Mass Storage support
[*] USB Mass Storage verbose debug
I will change the one "modul" entry to an "built-in" entry and try it again
