The "SCSI" driver used by the USB interface drivers will only handle
8 partitions per LUN. Sorry.

This is a common gotcha!

Same goes for IDE drives first configured on plain old PATA
interfaces and then swapped onto "RAID" controillers as ordinary
discs. All drivers other than "native" IDE tend to use SCSI.

So don't put more than 8 partitions on a hard drive if it's ever
likely to wander to another interface.

Somebody may have alternative drivers for the USB to e.g. force
higher partitions into the address space of another LUN. But that is
quite likely to break a great deal of other software!
