+	  This means that you can have more than 4 of a single type
+	  of device (like demuxes and frontends) per adapter, but udev
+	  will be required to manage the device nodes.

-
-SUPPORTED HARDWARE
-------------------
-
-This driver is intended for use with hardware having USB ID 05e1:0408.
-Two kinds of EasyCAP have this USB ID, namely:
-
-    *  EasyCAP USB 2.0 Video Adapter with Audio, Model DC60,
-       having input cables labelled CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
-
-    *  EasyCAP002 4-Channel USB 2.0 DVR, having input cables labelled
-       1, 2, 3, 4 and an unlabelled input cable for a microphone.
-
-
-BUILD OPTIONS AND DEPENDENCIES
-------------------------------
-
-Unless EASYCAP_DEBUG is defined during compilation it will not be possible
-to select a debug level at the time of module installation.
-
-
-KNOWN RUNTIME ISSUES
---------------------
-
-(1) Intentionally, this driver will not stream material which is unambiguously
-identified by the hardware as copy-protected.  Normal video output will be
-present for about a minute but will then freeze when this situation arises.
-
-(2) The controls for luminance, contrast, saturation, hue and volume may not
-always work properly.
-
-(3) Reduced-resolution S-Video seems to suffer from moire artefacts.
-
-
-INPUT NUMBERING
----------------
-
-For the EasyCAP with S-VIDEO input cable the driver regards a request for
-inputs numbered 0 or 1 as referring to CVBS and a request for input
-numbered 5 as referring to S-VIDEO.
-
-For the EasyCAP with four CVBS inputs the driver expects to be asked for
-any one of inputs numbered 1,2,3,4.  If input 0 is asked for, it is
-interpreted as input 1.
-
-
-MODULE PARAMETERS
------------------
-
-Three module parameters are defined:
-
-debug      the easycap module is configured at diagnostic level n (0 to 9)
-gain       audio gain level n (0 to 31, default is 16)
-bars       whether to display testcard bars when incoming video signal is lost
-           0 => no, 1 => yes (default)
-
-
-SUPPORTED TV STANDARDS AND RESOLUTIONS
---------------------------------------
-
-The following TV standards are natively supported by the hardware and are
-usable as (for example) the "norm=" parameter in the mplayer command:
-
-    PAL_BGHIN,    NTSC_N_443,
-    PAL_Nc,       NTSC_N,
-    SECAM,        NTSC_M,        NTSC_M_JP,
-    PAL_60,       NTSC_443,
-    PAL_M.
-
-In addition, the driver offers "custom" pseudo-standards with a framerate
-which is 20% of the usual framerate.  These pseudo-standards are named:
-
-    PAL_BGHIN_SLOW,    NTSC_N_443_SLOW,
-    PAL_Nc_SLOW,       NTSC_N_SLOW,
-    SECAM_SLOW,        NTSC_M_SLOW,        NTSC_M_JP_SLOW,

-
-WHAT'S TESTED AND WHAT'S NOT
-----------------------------
-
-This driver is known to work with mplayer, mencoder, tvtime, zoneminder,
-xawtv, gstreamer and sufficiently recent versions of vlc.  An interface
-to ffmpeg is implemented, but serious audio-video synchronization problems
-remain.
-
-The driver is designed to support all the TV standards accepted by the
-hardware, but as yet it has actually been tested on only a few of these.
-
-I have been unable to test and calibrate the S-video input myself because I
-do not possess any equipment with S-video output.
-
-
-UDEV RULES
-----------
-
-In order that the special files /dev/easycap0 and /dev/easysnd1 are created
-with conveniently relaxed permissions when the EasyCAP is plugged in, a file
-is preferably to be provided in directory /etc/udev/rules.d with content:
-
-ACTION!="add|change", GOTO="easycap_rules_end"
-ATTRS{idVendor}=="05e1", ATTRS{idProduct}=="0408", \
-	MODE="0666", OWNER="root", GROUP="root"
-LABEL="easycap_rules_end"
-
-
-MODPROBE CONFIGURATION
-----------------------
-
-The easycap module is in competition with the module snd-usb-audio for the
-EasyCAP's audio channel, and its installation can be aided by providing a
-file in directory /etc/modprobe.d with content:
-
-options easycap  gain=16 bars=1
-install easycap /sbin/rmmod snd-usb-audio; /sbin/modprobe --ignore-install easycap
-
-
-ACKNOWLEGEMENTS AND REFERENCES
-------------------------------
-This driver makes use of information contained in the Syntek Semicon DC-1125
-Driver, presently maintained at http://sourceforge.net/projects/syntekdriver/
-by Nicolas Vivien.  Particularly useful has been a patch to the latter driver
-provided by Ivor Hewitt in January 2009.  The NTSC implementation is taken
-from the work of Ben Trask.

- *

- *
- * This LIRC driver provides access to the TechnoTrend USB IR Receiver.
- * The receiver delivers the IR signal as raw sampled true/false data in
- * isochronous USB packets each of size 128 byte.
- * Currently the driver reduces the sampling rate by factor of 8 as this
- * is still more than enough to decode RC-5 - others should be analyzed.
- * But the driver does not rely on RC-5 it should be able to decode every
- * IR signal that is not too fast.
