Debian Packages:
hotplug
usbview
usbutils
See Chapter 61 for details on mounting USB devices
using udev.
USB is well supported in Debian. USB allows plug-n-play functionality
of many devices. Installing hotplug
(or the older
usbmgr) will install a daemon that monitors the USB ports
and install the appropriate modules when devices are plugged in, while
also noting when they are removed. The usbview command
will display the tree of USB devices connected in a window, while the
lsusb command lists in a terminal the usb devices. The
usbmodules command will list the drivers that might be able
to manage interfaces on currently plugged in USB devices.
For USB devices simply connect them to the USB socket and
hotplug
will notice the new device and load the
appropriate modules. (The alternative usbmgr daemon will
beep twice as it notices new devices.) The lsusb command
will show that the device is recognised. What happens next depends on
the type of the device.
The basic kernel module required to use USB at all is
usbcore, the bottom layer of USB support. It should
automatically be loaded by your kernel.
Further information about USB under GNU/Linux is available from
https://www.linux-usb.org/. In particular, see
https://www.linux-usb.org/USB-guide/book1.html.
Generally, newer kernels are required. For example, with
kernel-image-2.4.16-686
a USB 20GB Hard Disk and USB DVD
Burner worked but a USB Printer did not. With
kernel-image-2.4.20-686
they all worked.
