LIBUSB_ERROR_TIMEOUT on Samsung Galaxy Note 2

[zeitkunst]

I followed the conversation on the recently-closed bug for Samsung devices (#29), but unfortunately I am still hit by the LIBUSB_ERROR_TIMEOUT bug. I'm on Debian Wheezy.

I'm on the latest revision of go-mtpfs, I believe:

nknouf@nomadicsounds go-mtpfs> git rev-parse HEAD 731851c9363ffa26206219b9fbec1897f0b3d9d1

The debug logs don't provide much info for me:

Any suggestions of what else to try?

What device is this? What happens if you pass -debug=mtp,usb,data on the
cmd line?

This is a Samsung Galaxy Note II (SGH-I317).

Here's the output of the command:

does it help if you run mtp-detect first?

However, here the strange thing: I had an old udev rule when I was trying to get this work in the past. If I have had a problem connecting, giving the errors above, and then if I run mtp-detect and unplug/replug in the device, then my udev rule fires and the device is mounted properly---most of the time. I can't quite figure out the conditions where this does not work. I wish I could provide a more reproducible answer.

Let me know if you need any more information.

[hanwen]

can you disable all udev rules relating to this device? It's possible that they interfere with what you're trying to do.

[asrail]

I had a similar issue with Galaxy SIII Mini which fixed updating libmtp to 1.1.6 from 1.1.5. He was using libmtp 1.1.3, probably too old to work.
Those Galaxy phones exposes the internal memory as a micro SD card, and the actual micro SD card as an external card.

For the OP, look for a backport version of libmtp or pick one newer from somewhere else.

[phpmoli]

updating libmtp to 1.1.6 did NOT solve my issue.
using:
debian-wheezy 7.1
libmtp 1.1.6-20 from debian-jessie-testing
compiled go-mtpfs myself without errors

mounted dir is empty, was working(!) for the first 5-6 times, none after, still after rebooted android and debian.

[labos-medialab]

Do you have also external SD Card plugged in? If you do please try removing it and then mounting again.

[phpmoli]

i dont have an sdcard.
but anyway, i realized that this protocol only works when the device in awake - which is a very questionable design choice to say at least.

[hanwen]

You can't connect to a sleeping device for security reasons.

To the other bugreport: more recent versions do not use libmtp, but a pure Go implementation of MTP. You may have more luck with that.

[intuited]

I have a Galaxy S3 SGH-I747M; laptop is running Ubuntu 12.04.3 LTS. I acquired go-mtpfs by running go get github.com/hanwen/go-mtpfs about 7 hours ago.

I've been having problems similar or identical to those described by the OP. I've discovered that my go-mtpfs invocation will succeed under certain circumstances.

Until recently, I had the backported mtp backend for GVFS installed via PPA. To successfully connect go-mtpfs, I had to

• plug the phone in and immediately run mtp-detect. This would work and also prevent GVFS from connecting to the phone.
• run mtp-detect again. It would hang on Attempting to connect device(s). I hit CTRL-C to cancel it.
• then run go-mtpfs. It would work. WIthout the second mtp-detect, it would fail (I don't recall exactly why).

Since this was super complicated, I ppa-purged the ppa:langdalepl/gvfs-mtp PPA and rebooted. Now I can just do go-mtpfs without having to run mtp-detect twice first. I still have to do that before GVFS attempts (unsuccessfully) to connect to the phone; if I wait too long after plugging in the phone, it will fail, IIRC with the same timeout error quoted by the OP.

This strategy seems to work consistently, although I've only just discovered that it's possible. Recommendations on ways to make mounting happen more smoothly? Can I write a udev rule to prevent GVFS from flailing and instead cause my phone to be mounted via go-mtpfs?

Thanks for this project, by the way. Until I discovered this, it was looking like I would have to root my phone, since GVFS (even in Ubuntu 12.10) can't create files on my phone's storage space (internal or external SD card), and adb push can't access the external SD card.

[hanwen]

I have no idea about udev. You'd have to ask around on the udev mailing lists?

[likewhoa]

Running into similar issue with my Nexus 6 phone. I will update issue with debug output on my end tomorrow. so far I am running both go-{mtpfs,fuse} from HEAD as of this posting. It seems this issue is not just for Samsung devices only.

[hanwen]

@likewhoa - can you open a separate issue? Samsung uses a different MTP stack, so typically exhibits separate problems.

[likewhoa]

@hanwen sure, I will this morning.
