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 reqested by options is shown only for the specified device, otherwise all present devices are dis-
       played.

       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

NAME

       lsusb - list USB devices

SYNOPSIS

       lsusb [ options ]

DESCRIPTION

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

OPTIONS

       -v, --verbose
	      Tells lsusb to be verbose and display detailed information about the devices shown.  This includes configuration descriptors for the
	      device's current speed.  Class descriptors will be shown, when available, for USB device classes including hub, audio, HID, communi-
	      cations, and chipcard.

       -s [[bus]:][devnum]
	      Show only devices in specified bus and/or devnum.  Both ID's are given in decimal and may be omitted.

       -d [vendor]:[product]
	      Show only devices with the specified vendor and product ID.  Both ID's are given in hexadecimal.

       -D device
	      Do  not  scan  the /dev/bus/usb directory, instead display only information about the device whose device file is given.	The device
	      file should be something like /dev/bus/usb/001/001.  This option displays detailed information like the v option; you must  be  root
	      to do this.

       -t     Tells lsusb to dump the physical USB device hierarchy as a tree. This overrides the v option.

       -V, --version
	      Print  version information on standard output, then exit successfully.

RETURN VALUE

       If the specified device is not found, a non-zero exit code is returned.

FILES

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