Typing in 'dmesg' in a terminal will show you something like

Code:
scsi2 : SCSI emulation for USB Mass Storage devices
  Vendor: LEXAR     Model: JUMPDRIVE SECURE  Rev: 2000
  Type:   Direct-Access                      ANSI SCSI revision: 02
SCSI device sda: 502880 512-byte hdwr sectors (257 MB)
sda: assuming drive cache: write through
 /dev/scsi/host2/bus0/target0/lun0: p1
Attached scsi disk sda at scsi2, channel 0, id 0, lun 0
Attached scsi generic sg0 at scsi2, channel 0, id 0, lun 0,  type 0
USB Mass Storage device found at 2

The line "SCSI device sda: 502880 512-byte hdwr sectors (257 MB)
sda: assuming drive cache: write through
" lets you know it is mounted as device /dev/sda, so you can then mount it as /dev/sda1 (1 being the first partition).

As root (su -) type

Code:
mkdir /mnt/usb
mount /dev/sda1 /mnt/usb
Your device is now mounted. If you want to enable write access, using your favorite text editor (I'm using vi in this example) open up /etc/fstab (as root) and add the following line:

Code:
/dev/sda1  /mnt/usb  vfat  noauto,users,owner,exec,umask=000   0 0
Save and exit. Now anytime you want to mount your device you can do so simply by typing "mount /dev/sda1". Hope that helps.

Hello, I have the same issue with the USB harddrive (using Mandrake 10.0), and I have a thread a couple pages down. My problem is that when I use dmesg, there is no reference to any sda. If you view my post "Autodetect", I placed the dmesg output relevant to USB. Thanks.

Discovering the device name for a usb drive

Hello,

Is there a way to programmatically determine what device (/dev/sdxx) a usb drive is mapped to? Specifically, I do not want to rely on dmsg: a script will be doing this, not a human. My question is for Linux 2.6.

Thank you,
Federico Sacerdoti

Well the physical devices count up from a in the order they are detected, i.e. the order they are plugged in, or if plugged in at boot, the order the kernel sees them. the 1,2,3... just refers to the physical partitions you have on the device. If you have udev installed on your system they are statically mapped until you unplug them. If heard someone tried to do this by parsing the output of dmesg. I don't think he ever got it to work.
