     usbd.conf -- usbd(8) configuration	file

     The usbd.conf file	is the configuration file for the usbd(8) daemon.  It
     provides information to allow execution of	userland commands on events
     reported by the usb(4) subsystem in the kernel.  Currently	the only
     events are	device attach and detach, but could in the future be extended
     to	include	power management functions.

     The configuration file consists of	a sorted list of entries.  Each	entry
     describes a set of	criteria commands.  When an event occurs, the criteria
     are checked and if	met, the commands for that event are executed through
     a shell.  The list	is sorted and scanned from top to bottom.  The first
     matching entry is used for	an event.

     Each entry	contains a number of fields.  There are	3 types	of fields: de-
     scriptive fields, selection criteria and commands to execute on events.
     The field names are case sensitive	and should be all lower	case.  Each
     field can have one	or more	arguments.

     The following fields are available:

     device string    Start a new entry.  string is an arbitrary string	used
		      for pretty printing.

     product id	      Product Id

     vendor id	      Vendor Id

     release id	      Release Id, also called revision Id sometimes.

     class id	      Device Class

     subclass id      Device Subclass

     protocol id      Device Protocol

     devname string   Device name, for example umass2, or ums0.	 These device
		      names can	contain	regular	expressions.  See regex(3) and
		      re_format(7).  The device	name that is matched can be
		      used in the commands below through adding	${DEVNAME}
		      somewhere	in that	string.

     String arguments may be quoted.  If a string argument contains a space or
     tab character it needs to be enclosed in single or	double quotes.	If an
     argument contains a single	or double quote, that quote needs to be	en-
     closed in double or single	quotes respectively.  See below	for examples.

     Numeric arguments can either be specified in decimal (42),	octal (052) or
     hexadecimal (0x2a).

     The values	for the	fields product,	vendor,	release, class,	subclass and
     protocol can be retrieved by killing the usbd daemon and running it with
     the -d and	-v flags.

     Commands to be executed when the action is	matched:

     attach string    Shell command to execute when a device is	attached.

     detach string    Shell command to execute when a device is	detached.

     A sample entry to rescan the SCSI bus on connection of a Iomega USB Zip

	device "USB Zip	drive"
	   product 0x0001
	   vendor  0x059b
	   release 0x0100
	   attach "/usr/bin/camcontrol rescan bus 0"

     To	start up moused	for a newly attached mouse:

	device "Mouse"
	   devname "ums[0-9]+"
	   attach "/usr/sbin/moused -p /dev/${DEVNAME} -I /var/run/moused.${DEVNAME}.pid"

     /etc/usbd.conf    The usbd	configuration file.

     usb(4), usbd(8), usbdevs(8)

     It	is currently not possible to use a selection criterion more than once.
     For example, it is	not possible to	specify	more than one vendor ID.
