+Description:
+		Each USB device directory will contain a file named
+		power/autosuspend.  This file holds the time (in seconds)
+		the device must be idle before it will be autosuspended.
+		0 means the device will be autosuspended as soon as
+		possible.  Negative values will prevent the device from
+		being autosuspended at all, and writing a negative value
+		will resume the device if it is already suspended.
+
+		The autosuspend delay for newly-created devices is set to
+		the value of the usbcore.autosuspend module parameter.

+Description:
+		Each USB device directory will contain a file named
+		power/level.  This file holds a power-level setting for
+		the device, one of "on", "auto", or "suspend".
+
+		"on" means that the device is not allowed to autosuspend,
+		although normal suspends for system sleep will still
+		be honored.  "auto" means the device will autosuspend
+		and autoresume in the usual manner, according to the
+		capabilities of its driver.  "suspend" means the device
+		is forced into a suspended state and it will not autoresume
+		in response to I/O requests.  However remote-wakeup requests
+		from the device may still be enabled (the remote-wakeup
+		setting is controlled separately by the power/wakeup
+		attribute).
+
+		During normal use, devices should be left in the "auto"
+		level.  The other levels are meant for administrative uses.
+		If you want to suspend a device immediately but leave it
+		free to wake up in response to I/O requests, you should
+		write "0" to power/autosuspend.

 * Raw text data format
 
-The '1t' type data consists of a stream of events, such as URB submission,
+Two formats are supported currently: the original, or '1t' format, and
+the '1u' format. The '1t' format is deprecated in kernel 2.6.21. The '1u'
+format adds a few fields, such as ISO frame descriptors, interval, etc.
+It produces slightly longer lines, but otherwise is a perfect superset
+of '1t' format.
+
+If it is desired to recognize one from the other in a program, look at the
+"address" word (see below), where '1u' format adds a bus number. If 2 colons
+are present, it's the '1t' format, otherwise '1u'.
+
+Any text format data consists of a stream of events, such as URB submission,
 URB callback, submission error. Every event is a text line, which consists
 of whitespace separated words. The number or position of words may depend
 on the event type, but there is a set of words, common for all types.
 
 Here is the list of words, from left to right:
+
 - URB Tag. This is used to identify URBs is normally a kernel mode address
  of the URB structure in hexadecimal.
+
 - Timestamp in microseconds, a decimal number. The timestamp's resolution
   depends on available clock, and so it can be much worse than a microsecond
   (if the implementation uses jiffies, for example).
+
 - Event Type. This type refers to the format of the event, not URB type.
   Available types are: S - submission, C - callback, E - submission error.
-- "Pipe". The pipe concept is deprecated. This is a composite word, used to
-  be derived from information in pipes. It consists of three fields, separated
-  by colons: URB type and direction, Device address, Endpoint number.
+
+- "Address" word (formerly a "pipe"). It consists of four fields, separated by
+  colons: URB type and direction, Bus number, Device address, Endpoint number.
   Type and direction are encoded with two bytes in the following manner:
     Ci Co   Control input and output
     Zi Zo   Isochronous input and output
     Ii Io   Interrupt input and output
     Bi Bo   Bulk input and output
-  Device address and Endpoint number are 3-digit and 2-digit (respectively)
-  decimal numbers, with leading zeroes.
-- URB Status. In most cases, this field contains a number, sometimes negative,
-  which represents a "status" field of the URB. This field makes no sense for
-  submissions, but is present anyway to help scripts with parsing. When an
-  error occurs, the field contains the error code. In case of a submission of
-  a Control packet, this field contains a Setup Tag instead of an error code.
-  It is easy to tell whether the Setup Tag is present because it is never a
-  number. Thus if scripts find a number in this field, they proceed to read
-  Data Length. If they find something else, like a letter, they read the setup
-  packet before reading the Data Length.
+  Bus number, Device address, and Endpoint are decimal numbers, but they may
+  have leading zeros, for the sake of human readers.
+
+- URB Status word. This is either a letter, or several numbers separated
+  by colons: URB status, interval, start frame, and error count. Unlike the
+  "address" word, all fields save the status are optional. Interval is printed
+  only for interrupt and isochronous URBs. Start frame is printed only for
+  isochronous URBs. Error count is printed only for isochronous callback
+  events.
+
+  The status field is a decimal number, sometimes negative, which represents
+  a "status" field of the URB. This field makes no sense for submissions, but
+  is present anyway to help scripts with parsing. When an error occurs, the
+  field contains the error code.
+
+  In case of a submission of a Control packet, this field contains a Setup Tag
+  instead of an group of numbers. It is easy to tell whether the Setup Tag is
+  present because it is never a number. Thus if scripts find a set of numbers
+  in this word, they proceed to read Data Length (except for isochronous URBs).
+  If they find something else, like a letter, they read the setup packet before
+  reading the Data Length or isochronous descriptors.
+
 - Setup packet, if present, consists of 5 words: one of each for bmRequestType,
   bRequest, wValue, wIndex, wLength, as specified by the USB Specification 2.0.
   These words are safe to decode if Setup Tag was 's'. Otherwise, the setup
   packet was present, but not captured, and the fields contain filler.
+
+- Number of isochronous frame descriptors and descriptors themselves.
+  If an Isochronous transfer event has a set of descriptors, a total number
+  of them in an URB is printed first, then a word per descriptor, up to a
+  total of 5. The word consists of 3 colon-separated decimal numbers for
+  status, offset, and length respectively. For submissions, initial length
+  is reported. For callbacks, actual length is reported.
+
 - Data Length. For submissions, this is the requested length. For callbacks,
   this is the actual length.
+
 - Data tag. The usbmon may not always capture data, even if length is nonzero.
   The data words are present only if this tag is '='.
+
 - Data words follow, in big endian hexadecimal format. Notice that they are
   not machine words, but really just a byte stream split into words to make
   it easier to read. Thus, the last word may contain from one to four bytes.
