4.22.3. Mounting Of USB Devices
Plugged USB devices will be detected automatically but must be mounted and unmounted ’by
hand’. When plugging an USB stick it is recognized as a SCSI block device. For this reason
is accomplished via device sd# for SuperFloppy devices or sd# Partition-number for devices
with a partition table. USB drives are treated as hard disks and addressed as sda1 and sdb1
if plugged in two USB ports. USB floppies are addressed via sda or sdb without specifying a
partition number.
Thus a first USB stick can be mounted to /mnt by executing
mount /dev/sda1 /mnt
A second one at the same would need
mount /dev/sdb1 /mnt
to be mounted. Devices are numbered in the sequence of plugging - first USB device = sda,
second USB device = sdb a.s.o. This means that device numbering is not fixed but depending
on the sequence of plugin. Unmounting is done via
umount /mnt
If using more that one USB device never mount all devices to the same directoy. Create
directories under /mnt for each device to be mounted. Make the directories by executing:
mkdir /mnt/usba
mkdir /mnt/usbb
Then specify the directories as destinations when mounting:
mount /dev/sda1 /mnt/usba
mount /dev/sdb1 /mnt/usbb
The content of the USB devices can be found at /mnt/usba res. /mnt/usbb. Unmounting
can be done via
umount /mnt/usba
umount /mnt/usbb
If an USB device has more partitions the device directories under /mnt have to reflect this
structure in subdirectories.
4.23. WLAN - Support For Wireless-LAN
When using PCI Cards please be sure to use a mainboard that at least complies to the speci-
fications of PCI 2.2. Older mainboards that only support PCI 2.1 or less can produce diverse
