NetBSDからMTPデバイスを使う

この記事は、NetBSD Advent Calendar 2016の6日目の記事です。

はじめに

AndroidなスマートフォンはMTP (Media Transfer Protocol) で 内蔵ストレージや挿し込まれたmicroSDカード等の中身をPCから見ることができます。 私の使っているXperia Z Ultraで言うと、どうやら内蔵ストレージは MTPでしか見ることができないようです。

と言うことで、NetBSDな常用ラップトップから、Xperia X Ultraの内蔵ストレージと microSDカードの中身を扱う方法を書いてみます。

libmtpを使う

一番簡単なのは、昔のMS-DOSのFAT領域を扱うmtoolsのような仕組みを使う方法です。 このようなツールは、一つは、pkgsrc/devel/libmtpで提供されています。 Xperia Z UltraをMTPモードに設定して、NetBSD/amd64なラップトップに接続してみます。 カーネル的にはデバイスドライバーはありませんので、ugen(4)として認識されます。


ugen0 at uhub0 port 5
ugen0: Sony C6833, rev 2.00/2.32, addr 11

libmtpをインストールして、Xperia Z Ultraが認識されるか試してみます。


$ cd /usr/pkgsrc/devel/libmtp
$ make install
$ mtp-detect
libmtp version: 1.1.12

inep: usb_get_endpoint_status(): Bad file descriptor

この次には、以下のように実行すると、ls相当のことができるはずです。


$ mtp-files

Device 0 (VID=0fce and PID=019c) is a SONY Xperia Z Ultra MTP (ID3).
mtp-files: Successfully connected

LIBMTP libusb: Attempt to reset device
LIBMTP PANIC: failed to open session on second attempt

OK.

最後にOKと出力されましたが、全くOKではありません。 何度か試しましたが、どうやらこのままでは動かないようです。

gPhoto2を使う

私の知っているもう一つのMTP実装は、gPhoto2 (pkgsrc/graphics/gphoto2とpkgsrc/deve/libgphoto2)です。 これもmtools的なツールです。


$ cd /usr/pkgsrc/graphics/gphoto2
# make install
$ gphoto2 -a
Abilities for camera             : SONY Xperia Z Ultra MTP (ID3)
Serial port support              : no

Capture choices                  :
                                 : Capture not supported by the driver

Delete selected files on camera  : yes
Delete all files on camera       : no
File preview (thumbnail) support : no
File upload support              : yes

どうやらエラーはなさそうですので、期待が持てそうです。 lsに相当することをしてみます。


$ gphoto2 -L

#922   track81.cdda.wav.mp3       rd   835 KB audio/mpeg

複数回繰り返しても、2回目以降エラーになることもないようです。 次にファイルを取り出してみます。最後のファイル#922を取り出してみます。


$ gphoto2 -p 922
Saving file as track81.cdda.wav.mp3

なぜかXperia Z Ultraを操作中には、成功するようです。 そのまま置いておくと、失敗しました。 mtools的な操作で、機動性には欠けますが、MTPでしか接続できないデバイスからも無事にファイルを取得できそうです。

今後の課題

FUSEを使ってmountできるようになれば便利そうですが、MTPはそもそもPOSIXがファイルシステムへ要求する仕様を満足していないそうですので、あまり使いやすくないかもしれません。
