Description-en: FUSE based filesystem for accessing MTP devices
jmtpfs is a FUSE and libmtp-based filesystem for accessing MTP (Media Transfer
Protocol) devices. It was specifically designed for exchanging files between
Linux (and Mac OS X) systems and newer Android devices that support MTP but
not USB Mass Storage.
.
The goal is to create a well-behaved filesystem, allowing tools like find and
rsync to work as expected. To enable certain Android apps to detect and use
the transferred files, MTP file types are set automatically based on file
contents using libmagic.
■jmtpfsのインストール
「MtpErrorCantOpenDevice」は先にMTPマウントされているときに出る。
$ sudo apt-get install -y jmtpfs
$ sudo mkdir /media/android
$ sudo jmtpfs /media/android/
Device 0 (VID=0b05 and PID=7772) is a Asus MemoPad 7 (ME572CL).
error returned by libusb_claim_interface() = -6LIBMTP PANIC: Unable to initialize device
terminate called after throwing an instance of 'MtpErrorCantOpenDevice'
what(): Can't open device
中止
■MTPでマウントしたままなので、アンマウントして再実行。
これで直接mpv動画プレイヤに渡せる。

正しく認識しているので修正の必要性は無いけど、「590f」を「7772」にするくらいかな。
