The standard Mass Storage Device protocol is used for USB devices such as hard disk drives, flash memory drives, memory card readers, and digital cameras. Such devices have a standard VFAT (MSWindows) file system.
The USB mass storage device is treated as a SCSI device so simply mount the SCSI device:
# mount -t auto /dev/sda1 /mnt
You should now be able to see and use the device as any other disk. If you already have a SCSI device then the USB device might be /dev/sdb1!
The kernel module []usb-storage drives USB mass storage devices and should be automatically loaded by hotplug. The kernel module []vfat is also required, and if it does not autoload then you will need to:
# modprobe vfat
You can run dmesg to check that the USB device has been found.
A sample setup of four USB devices includes a USB mouse, HP Printer/Scanner/Copier with a card reader, a digital camera, and a flash memory drive (3System USB flash disk). The /etc/fstab includes:
/dev/sda1 /hpcard auto rw,user,noauto 0 0 /dev/sdb1 /camera auto rw,user,noauto 0 0 /dev/sdc1 /flash auto defaults,user,noauto 0 0Then any user can mount, for example, /hpcard, when a memory card has been inserted into the card reader. A problem is that unless the camera is connected before the flash drive after a reboot, the mappings end up being reversed!
The devices look like any other hard drive device so you can run fdisk on it and reorganise partitions:
# fdisk /dev/sda
You can also format the partition(s) on the device, usually with a DOS/FAT filesystem:
$ mkfs -t vfat /dev/sda1
