[MTP to Android device] libUSB timeout when copying files

[fdelente]

Hello.

After mounting my Samsung Galaxy S4 Mini with go-mtps and starting to copy files, I get

2014/02/12 13:02:12 starting FUSE.
2014/02/12 13:02:35 sending file "file.mp3" to device: 124996940 bytes.
2014/02/12 13:02:44 fatal error LIBUSB_ERROR_TIMEOUT; closing connection.
2014/02/12 13:02:49 SendObject failed LIBUSB_ERROR_TIMEOUT

I have disabled the lock screen on the phone, but it doesn't solve the problem

I don't think this is gentoo-related, but I haven't found any solution by googling and the Samsung tech support told me everything was fine in Linux with MTP, can anybody here give me a hand?

Thanks!

Hello!
Everything is fine with MTP in Linux?
That's totally not my experience so far. It seems to suck. Hard!
I am using latest KDE and a generally ~amd64 system along with libmtp-9999 and still the connection is so bad that I don't bother using it. If you just want to access your ExtSD, try something like USBMassStorageEnabler from PlayStore or search XDA for something similar. For syncing folders, I just discovered BTSync today, there is an ebuild floating around somewhere (yeah, why the heck isn't this in portage?).

I went around the problem by installing an SSH server on the phone, and scp-ing my files from linux... but barely getting 1 Mb/s instead of around 20 Mb/s in USB mode... :^(

[Martux]

Really try btsync. There's ann ebuild somewhere. Works flawlessly for me. Or Plain old USB mode. Btw, with my new note 3,mtp seems to just work. Seems to be heavily device dependent if you have issues or not.

Martux, as you're a KDE user, have you tried kde-misc/kio-mtp? It works well on my main laptop (~amd64). I can copy files from phone to laptop and vice versa without problems.

Yes, Fitzcarraldo. As I said this seems to work very device-specific. With my Note 2 it was driving me crazy, with the Note 3 it just works. Since some days I exclusively use BTSync (http://www.bittorrent.com/intl/sync) and it's just a charme The gentoo part runs as daemon, very nice.

I have a Samsung Galaxy Note II, and that works fine with kio-mtp (even though mtpfs is unreliable), so I'm surprised you had problems with your Note II. I'm running KDE 4.12.2 in Gentoo ~amd64 on the following hardware:

- Intel Core i7 720QM (1.6 GHz)
- 4 GB DDR3
- 15.6″ LCD (1920×1080)
- ATI Mobility Radeon HD 5650, 1 GB GDDR3
- 320 GB HDD
- Atheros Communications AR8131 Gigabit Ethernet controller
- Intel WiFi Link 5300
- Broadcom BCM2046 Bluetooth Device
- 4 x USB 2 ports

Yes, libmtp-9999 here. Is that option you selected in the kernel?

Both MS and the vendors are at fault for MTP. MS gets dinged for something that is not well thought out, and the vendors get blame for not executing and for only debugging against windows installs. I found all this out when I tried it with my Nexus 7 tablet and then started googling around about all of the errors I was getting.

I just use the ES File Explorer from Google Play and do all of the transfers with it on wifi from samba shares.

Mtp never worked for me.

Fortunatelly you have adb, ssh, ftp, bluetooth (ugh...), owncloud and a few other proprietary options which I don't care about.

If you find the correct combo you don't even need to worry about the sync'ing, unlike with mtp. And it actually workS.

Edited: mtp always reminded me of gphoto and that stuff. It really doesn't serve any purpose that's not covered by any other better more general software/protocol that actually works and is usable in a number of architectures instead of just beeing valid for $RANDOMTOY

[Martux]

Here's maybe another nice option (at least for KDE users): kdeconnect.
There's no official ebuild, but there's a live ebuild around. Since today the "browse device" option is working very well. It's working via sftp and just integrates into dolphin

Have you tried with the dolphin integration? Should work!

i've a Galaxy S4
and the only thing i did was installing following packeges

[Roman_Gruber]

I just wonder why you dont use android debug bride and make a full backup or copy the files in bash?

Works quite well on google nexus 4. And i think this feature is android specific so it should work on any newer android.

could never get it really working that properly


instead I've been using the app AirDroid (transfers via WLan)


simple drag'n'drop there


and for those cases (emergencies) where files really need to be transferred adb push usually is enough

Currently I'm using the mtp:// feature of my filebrowser Thunar, with some Android CM12.1 (5.1). That works with some drawbacks:

* Only after unlocking the phone (security feature I agree with), and sometimes continues working after locking, but sometimes not. In that case only re-plugging USB works or manually disabling/enabling MTP in the device which is annoying.
* Other apps have no idea about mtp:// . That means I can't even use a PDF-Reader or Picture-Viewer. I guess Thunar's MTP is done by gvfs, maybe also Gtk apps like geeqie (pictures) don't use gvfs, I did not step into that further.

However I would prefer a mount, say fuse would be an option.
What fuse module is recommended today as there are a few around:

@Massimo B.

I'm using sys-fs/simple-mtpfs with my N4 and N5,
and it works quite good and stable.

I tried sys-fs/mtpfs some time ago, but without success (very unstable connection or none)...

How do you deal with disconnection when the phone is ringing? Just unplug, re-plug later? Or umount first?

personal expierence:

mtp did not worked for me in windows 7 (with my nexus 7) and I had issues on gentoo. I did not got it to work where adb worked out of the box instantly. As I needed adb for other things also, and when you want to tweak your android, its the only way here. I doubt you can access special folders with mtp. its limited to only a few folders on teh /sdcard mountpoint afaik.
android debug bridge with
adb push file
adb pull file
works quite well

and adb gives a line at each transfer how fast it was. and you can issue adb devices to see if your phone is connected in the first place.
