Galaxy A5 2016 USB reset when trying to mount with simple-mtpfs #47

Closed vitalif closed 8 years ago

vitalif commented 8 years ago

Hi! I don't know if this a problem of simple-mtpfs or the phone itself... But when I'm trying to mount my galaxy A5 2016 (SM-A510F) (stock firmware) with simple-mtpfs, it results in a usb reset O_o. dmesg from the phone is in the attachment. mtp_reset.txt

MTP is obviously not mounted after reset, simple-mtpfs says: LIBMTP PANIC: Trying to dump the error stack of a NULL device! (this is because the device file in /sys/bus/usb vanishes)

This does not occur when mounting the phone with, for example, jmtpfs or android-file-transfer. But jmtpfs is very buggy and android-file-transfer fails to mount this phone read-write because it says "your device does not have android EditObject extension, mounting read-only".

Maybe it is possible to fix simple-mtpfs?

Yes, it resets the device due to certain timeouts I encountered some time ago. See mtp-device.cpp... If this is the problem, I'll happily remove it, if it works correctly nowadays...

Interesting.. after removing both lines with smtpfs_reset_device it works. But why does it work with other phones with resets and does not work with A510F? O_o

Once, I have some spare time, I will have a look at this, for sure. Thanks for the heads up.

Can you try libmtp workaround from #37 ?

vitalif commented 8 years ago

Yes that's what I've done first :) it doesn't help.

I use Sony Xperia X (F5121). I have the same issue. I removed https://github.com/phatina/simple-mtpfs/blob/master/src/simple-mtpfs-mtp-device.cpp#L199, but can't mount. I also removed https://github.com/phatina/simple-mtpfs/blob/master/src/simple-mtpfs-mtp-device.cpp#L153, then work correctly.

Thank you guys! With testing and fixes.. I'll push these asap.

I use Sony Xperia Z2 and can mount MTP only when smtpfs_reset_device on https://github.com/phatina/simple-mtpfs/blob/master/src/simple-mtpfs-mtp-device.cpp#L153 is removed. smtpfs_reset_device on line 199 can be kept in my case.
