Trying again, but last time I had problems even beforee mounting.

DSL insmodded usbcore and usb-uhci

sudo modprobe usb-storage

Produced about 10 lines of messages about
usb-uhci.c:  interrupt, status 2, frame# (variable number)
usb bulk control timeout
Five more of these lines with status 3 this time and a timeout after the 
third followed by a prompt.

I hit Enter and got a prompt.

I tried to mount /dev/sda1 (this is wrong) and it crashed.

I am rebooting (BL boots much faster).

sudo mount /mnt/sda1 gives me an error message saying something about not 
finding /mnt/sda1 in /etc/fstab

fstab has a line about
/dev/sda1 /mnt/usbdrive auto user,mount/exec,umask-000 00

less /etc/fstab crashed DSL

I think usb-storage is causing the problem, not mount.
I got a crash another time by typing ps after modprobing usb-storage.


One time I tried, without insmodding usb-storage:
sudo mount /dev/sda1

It did not crash.  But it said READ CAPACITY failed and No medium found 
(because I did not have the usb-storage driver loaded, of course).

This time I first used the DOS USB driver to copy all the photos to hard 
drive before playing with linux.

I have the camera set to PC and turned on before booting.

This camera does not seem to work with usb-storage.

I can try the other camera with an empty CF card, but we don't even know 
how to use that one with DOS USB drivers.

I need to read more about USB drivers for cameras.
