 See the "INSTALL" file.
 
 
 Initiator and Responder
 -----------------------
 
 libmtp implements an MTP initiator, which means it initiate
 MTP sessions with devices. The devices responding are known
 as MTP responders. libmtp runs on something with a USB host
 controller interface, using libusb to access the host
 controller.
 
 If you're more interested in the MTP responders, gadgets like
-MP3 players, mobile phones etc, look into:
-- MeeGo:s Buteo Sync:
-  https://github.com/nemomobile/buteo-mtp
-  https://wiki.merproject.org/wiki/Buteo/MTP
-- Android has an MTP responder implementation:
-  https://android.googlesource.com/platform/frameworks/base/+/master/media/jni/
-- Ubuntu/Ricardo Salveti has mtp-server and libmtp-server going:

+MP3 players, mobile phones etc, look into MeeGo:s Buteo Sync:

 Heritage
 --------
 
 libmtp is based on several ancestors:
 
 * libptp2 by Mariusz Woloszyn was the starting point used
   by Richard A. Low for the initial starter port. You can
   find it at http://libptp.sourceforge.net/

 FAQ: Common Problems
 --------------------
 
 Some MTP devices have strange pecularities. We try to work around
 these whenever we can, sometimes we cannot work around it or we
 cannot test your solution.
 
-* Android locked screen: some devices just report zero files
-  and no storages when the device screen is locked, it looks like
-  so:
-
-  mtp-detect
-  Device 0 (VID=04e8 and PID=6860) is a Samsung Galaxy models (MTP).
-  Attempting to connect device(s)
-  Error 1: Get Storage information failed.
-  Device: SHV-E210K
-  LIBMTP_Get_Storage(): No data available
-  OK.
-
-  This is probably so as not to allow the MTP access to be used
-  as a "backdoor" into the device. Unlock the device before listing
-  files, set the autolock to some large value or disabled if it
-  disturbs you, you are causing this to yourself, or should we say
-  that your vendor is prioritizing security and privacy over
-  ease-of-use. (You may talk to your vendor about this.)
-
 * mtp-* tools doesn't work because someone else is already hogging
   the device
 
   This is a common problem, the most common case could be that
   gphoto2 (which can also talk PTP/MTP) is taking over the device
   as soon as it's plugged in. Some distributions are configured that
   way. Counter it like this:
 
   gvfs-mount -s gphoto2
 
   Then re-attach the device.
 
-  Sometimes some gvfs daemons are running on the
-  system and hogging the device, try stopping them
-  with something like these commands:
+  Sometimes the "gvfs-gphoto2-volume-monitor" is running on the
+  system and hogging the device, try something like:
 
-  killall gvfs-mtp-volume-monitor
-  killall gvfs-gphoto2-volume-monitor
+  pkill gfvs-gphoto2-volume-monitor
 
   Then plug in the device and issue "mtp-detect" to figure out if
   this may be the case.
 
 * Generic MTP/PTP disconnect misbehaviour: we have noticed that
   Windows Media Player apparently never close the session to an MTP
   device. There is a daemon in Windows that "hooks" the device
   by opening a PTP session to any MTP device, whenever it is
   plugged in. This daemon proxies any subsequent transactions
   to/from the device and will never close the session, thus

   such devices and you cannot expect to have command line tools
   like the mtp examples work with them. You could implement new
   example programs that just call to a mediating daemon like the
   Windows MTP stack does. (And change all programs using libmtp
   directly today.)
 
   If this bug in your device annoys you, contact your device
   manufacturer and ask them to test their product with some libmtp
   program.

 * Samsung Android 2.3.x devices: these have a special MTP stack
   with some specific bugs that we have maybe nailed down now.
   It suffers from an "immediate connect" syndrome, i.e. you have
   to connect to the device within 7 seconds of plugging in, or it
   will go numb. This also goes for command-line activity with
   the example programs, so this device is better used with a
   GUI tool like Rhythmbox, gnomad2...
 
 * Generic USB misbehaviour: some devices behave badly under MTP
   and USB mass storage alike, even down to the lowest layers

  1. Plug in the device.
  2. USB-mass storage folder will open automatically.
  3. Unmount the device.
  4. Run mtp-detect. It will most likely fail the first time.
  5. Run mtp-detect again, it might work this time, or fail. Keep running
     till it works. 99% it works by the third try.
  6. Once mtp-detect gives you an "Ok", open either Rhythmbox or Gnomad2,

-This will tell usb-storage to ignore this device when it's inserted

 Now none of you USB disks, flash memory sticks etc will be
 working (you just disabled them all). However you *can* try
 your device, and it might have started working because there
 is no longer a USB mass storage driver that tries to hook onto
 the mass storage interface of your device.
 
 If not even blacklisting works (check with
 "lsmod | grep usb-storage"), there is some problem with

 SKETCH OF AN OVERVIEW
 ---------------------
 
 Draft agenda for a talk on MTP devices submitted for the Android
 builders summit, might come to recycle this:
 
 - Protocol overview
   - Transactional filesystem - no corruption due to unplugged cables!
-  - The host and the device can access the files simultaneously, the
-    device will always "own" the physical file system and proxy the
-    host (MTP initiator).
 - libmtp interface
 - relation to libgphoto2
 - User expectations fall short:
   - Not really a mountable filesystem.
   - Streaming does not work. (Size needs to be known beforehand due to
     transactional nature.)
-  - GVFS MTP backend to the rescue.
 - Device sins
-  - Using the same VID/PID for several modes, some of which are not MTP.
-    HTC Zopo, HD2, Bird (0x0bb4/0x0c02). Thanks for that, now we cannot
-    detect the protocol from just VID+PID but have to examine the interfaces.
   - Android bugs
   - Samsungs special Android MTP stack
   - SonyEricsson Aricent stack for Xperia Androids pre 4.0, broken headers!
   - Flat access model vs hierarchical, how Android uses MTP as an hierachical
     file system while it was previously a flat database.
-  - Old paradigm: scan the entire non-hierarchical storage for all content,
-    build a cache to speed up the (USB 1.1!) link. Usually all files were
-    stored in the root folder or a single folder named "/Music" or similar.
-  - Android introduced deeply nested folder hierarchies, not seen before
-    on MTP devices.
-  - Microsoft not using the complete metadata dump feature of the MTP
-    protocol (once introduced by creative) instead they walk directories
-    separately.
-  - So caching a big device will take long time and/or timeout.
-  - Go-MTPFS (FUSE) and GVFS MTP - doing the partial directory walk rather
-    than caching all files.
-  - Especially Android devices nowadays assume that
-    you want to index a folder at the time, whereas older MTP devices (such
-    as those from Creative) would assume that you wanted to index the entire
-    device as it was plugged in, and device firmware is now ever more tailored
-    toward per-folder filetree walking. This makes it harder for the library
-    to provide the right abstractions: do we provide an API for indexing the
-    whole device which is unacceptably slow on new devices, or do we provide
-    an API for indexing a directory at the time which will somehow work on
-    older devices too? Shall we deprecate the older API?
 - Detecting from vendor extension, can fix in newer extensions!
 - Autoprobing on Linux
   - Color devices do not like autoprobing
   - Devices need different PIDs for every alternative interface due to
     the Windows USB stack.
   - Multimode USB - one PID for each mode due to Windows limitations not
     applicable to Linux, SONY devices have ~5 different PIDs for a single
     device.
-  - Mode switch devices? Maybe we do this wrong.
-- MTPZ, came and went. Apparently deprecated by Microsoft with Windows
-  Phone 8.
