Clik USB drive - Linux StepByStep

Submitter: Marianne Taylor

Using a USB storage device requires that your kernel have the following compiled as modules (or internal to the kernel):

CONFIG_USB
CONFIG_USB_UHCI
CONFIG_USB_OHCI
CONFIG_USB_STORAGE

These devices also use SCSI, so remember to make sure your kernel supports SCSI generic and SCSI disk. Once you have a suitable kernel, proceed.

You must determine which adapter driver to use. Generally, an Intel or Via motherboard will need usb-ohci.o; motherboards by Compaq, OPTi, SiS, and ALI need uhci.o (so do iMacs). To ensure you have the correct apadter, examine /proc/pci like so:

cat /proc/pci|grep -i usb

If the entry is of the form 0xe400, use Uhci.o; if it is 0xee000000 then you should use usb-ohci.o. Failing that, just try one or both.

To get the device working:

Load the SCSI drivers

modprobe sg
modprobe ide-scsi

Load the USB drivers

modprobe usbcore
modprobe usb-uhci/usb-ohci
modprobe usb-storage

If you wish to have these modules loaded at boot, add them to modules.conf/conf.modules in /etc

Create an fstab entry

echo "/dev/sda4 /mnt/usb vfat noauto,user 0 0" >> /etc/fstab

Create the mount-point

mkdir -p /mnt/usb

Mount the drive

mount /mnt/usb
