Since /etc/fstab contains a line starting in
/dev/sda1 /mnt/usbdrive

might I want to
sudo mount /mnt/usbdrive

rather than   /mnt/sda1 ?

But usb-storage seems to be causing problems and causing anything done 
afterwards to crash.

This requires scsi_mod and sd_mod but doesn't modprobe take care of this?

Does DSL actually have any scsi (emulation) support?

I found some other site about USB and linux suggesting I used dc-2xx 
(driver?  program?) for the HP Photosmart.


I will try BL2 again some time with sd_mod before usb-storage.
