My persistent home directory on a USB drive is not detected in Knoppix 3.8.1.

Knoppix boots successfully, and an icon for "uba1" lets me access everything on the USB drive, but the partition is not mounted as /home. I tried cheat codes home=/dev/sda1, home=/dev/uba1, and home=/mnt/uba1.

Plugging the drive into the PC's USB port instead of a hub does not help.
fdisk /dev/uba shows one partition of type 83. The /home works works fine under Knoppix 3.7.
