     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:
     descriptive 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
     enclosed in double or single quotes respectively.	See below for exam-

     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.


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