SYSTOOL(1)						      General Commands Manual							SYSTOOL(1)

NAME

       systool - view system device information by bus, class, and topology

SYNOPSIS

       systool [options [device]]

DESCRIPTION

       Calling systool without parameters will present all available bus types, device classes, and root devices.

       When  device  is  supplied,  the information requested by options is shown only for the specified device, otherwise all present devices are
       displayed.

       systool uses APIs provided by libsysfs to gather information.  systool runs only on Linux systems running kernels 2.5 or  later,  with  the
       sysfs filesystem mounted.

OPTIONS

       -a     Show attributes of the requested resource

       -b bus Show information for a specific bus

       -c class
	      Show information for a specific class

       -d     Show only devices

       -h     Show usage

       -m module_name
	      Show information for a specific module

       -p     Show absolute sysfs path to the resource

       -v     Show all attributes with values

       -A attribute
	      Show attribute value for the requested resource

       -D     Show only drivers

       -P     Show device's parent

lsusb(8)							Linux USB Utilities							  lsusb(8)

NAME

       lsusb - list all USB devices

SYNOPSIS

       lsusb [options]

DESCRIPTION

       lsusb is a utility for displaying information about all USB buses in the system and all devices connected to them.

       To make use of all the features of this program, you need to have Linux kernel 2.3.15 or newer which supports the /proc/bus/usb interface.

OPTIONS

       -v     Tells lsusb to be verbose and display detailed information about all devices.

       -vv    Tells lsusb to be very verbose and display even more information (actually everything the PCI device is able to tell).

       -s [[<bus>]:][<devnum>]]
	      Show only devices in specified bus and devnum.

       -d [<vendor>]:[<product>]
	      Show only devices with specified vendor and product ID. Both ID's are given in hexadecimal and may be omitted.

       -p <procpath>
	      Use another path instead of /proc/bus/usb.

       -D <device>
	      Do not scan the /proc/bus/usb directory, instead display only information if the device whose device file is given.

       -t     Tells lsusb to dump the physical USB device hierarchy as a tree.

FILES

       /usr/share/hwdata/usb.ids
	      A list of all known USB ID's (vendors, products, classes, subclasses and protocols).

       /proc/bus/usb
	      An  interface  to USB devices provided by the post-2.3.15 Linux kernels. Contains per-bus subdirectories with per-device files and a
	      devices file containing a list of all USB devices.
