Dody-

I've had success trying mounting a few devices (e.g., /dev/stdb, /dev/stda and other /dev/std*). Sometimes I have to try a few before I eventually find the usb that I've just plugged into. This seems to work pretty well when memory sticks are involved.

Does this help at all?

ok sorry,
when i run the "lsusb" command i get: Bus 001 Device 002: ID xxxxxx Sandisk Corp.
so the device is recognized.
after running the "dmesg | grep -i scsi or usb" ..i get:
SCSI subsystem initialized
scsi0: SCSI emulation for USB Mass Storage devices

or

(long list)
Initializing USB Mass Storage driver...
usb-storage: device found at 2
usbcore: registered new driver usb-storage
USB Mass Storage support registered
usb 1-1: reset full speed USB device using uhci_hcd and address 2
usb-storage: device scan complete

i realized that i didn't have "sda1" on /dev...so i ran the MAKEDEV sda command
but after running the mount command i get /dev/sda1 is not a block device...
i also reset the usb-storage in the kernel with the "modprob" command.
nothing

thnx

Dody-

I think it might help to have some configuration information. For example, what distro do you use and what sort of computer acts as the platform? Don't know if that'll be what helps me figure this out, but maybe it'll trigger someone else. You have to figure that someone else out there has seen this...
