first, lock for the "usb-storage" modul with "lsmod". if you can't find the modul, probe with "modprobe usb-storage"
 
when the modul loadet, you can mount the usbdevice with "mount /dev/sdaX /mnt"

Code:

mkdir /mnt/flash

Code:

mount -t vfat /dev/sda1 /mnt/flash

 
Well,
 
after
 
lsmod usb-storage O.K. (ergo present)
hotplug usb
mount -t vfat /dev/sdax /mnt/usb still do'nt work ...
 
please help
 
thanks
 
P.S. Mandrake 9.1

THANKS!

Can you see your device in /proc/bus/usb/devices ?
post this file if in doubt.

You should be good to go.
if /dev/sda1 does'nt work try /dev/sdb1.
