Very Computer

Hello!

I upgraded my kernel to 2.4.1 to get USB support.  I can now use the
'photopc' program to talk to my Nikon 880 USB camera on the USB
interface!

I also bought a Sandisk Compactflash USB reader device -- which is
supported in Linux -- and everything 'looks good' in all the places
I look for messages, but when I make an effort to mount /dev/sda
I get the message:

mount: /dev/sda has wrong major or minor number  

I have no idea what I may be doing wrong.  Here is a small amount of
messages that show that things should be OK:

hub.c: USB new device connect on bus1/2, assigned device number 2
usb.c: kmalloc IF c688b4c0, numif 1

Currently, I have the following in my /etc/fstab file for this
device:

none                    /proc/bus/usb           usbdevfs defaults 0
0    

This looks strange to me.  I image that instead of 'none' I
should have a valid device name, but every one of the '/dev/sda'
devices don't seem to work.

I am so close to success I can almost taste it!

Any help?

Have you included SCSI-emulation in your kernel ?
I'm using it with my Fujifilm 1400Zoom. The camera is connected to the
computer via USB and the Smartmedia Flash-card registers itself as
/dev/sda1. Thius wont work without SCSI-emulation and USB Mass-storage
though. Include SCSI-emulation, SCSI support and generic scsi support and
try again.

I think you should mount /dev/sda1 instead of /dev/sda. Also, the file
system is vfat. So:

mount -t vfat /dev/sda1 (your mount point)

Have you loaded the module usb-storage before you tried to mount the
compact flash?

Good luck

Thanks for offering advise!

Actually, with the help of another responder, who showed me what
his kernel settings looked like for SCSI, I managed to get this
working with '/dev/sda1' without even using 'vfat' (though I will
try that to see what difference it makes).

What I think the essential difference was that I was missing is
that I had NOT compiled 'SCSI drive support' -- thinking that I had
no true SCSI devices and definitely not a SCSI 'drive'!
