无法使用简单的MTPFS安装Galaxy S7（使用S4它用于工作正常） -- connection-issues 领域 和 usb-connection-mode 领域 和 mount 领域 和 mtp 领域 和 usb-mass-storage 领域 android 相关 的问题

I would like to mount my Samsung Galaxy S7 (SM-G930F) to an folder using simple-mtpfs and I cannot do it as I used to (on previous Fedora and older Galaxy S4).

If I simply plug S7 to my computer, I can browse it using Nautilius, but I cannot access it in terminal as ordinary folder, what is exactly what I want to achieve.

Every time I plug S7 I check twice that it works in MTP mode, so that isn't the problem.

In the past, I simply plugged the phone and typed something as:

$ simple-mtpfs /home/adam/S7 

Now, I can perform it and even my phone ask me to confirm MTP choice, but the catalogue S7 is still empty.

I also tried to mount it as root or ordinary user and by device number, but with no result.

# simple-mtpfs --list-devices 1: SamsungGalaxy models (MTP)  $ simple-mtpfs --device 1 /home/adam/S7 # simple-mtpfs --device 1 /media/s7  $ simple-mtpfs /dev/libmtp-3-1 /home/adam/s7 # simple-mtpfs /dev/libmtp-3-1 /media/s7 

I even tried to do it by udev rules:

# dmesg | tail [16821.258485] usb 3-1: Product: SAMSUNG_Android [16821.258487] usb 3-1: Manufacturer: SAMSUNG [16821.258489] usb 3-1: SerialNumber: 98867?????????????

Content of /etc/udev/rules.d/10-phone.rules is set to:

SUBSYSTEM=="usb", ATTR{idVendor}=="04e8", ATTR{idProduct}="6860", SYMLINK="S7" 

After reloading rules I have /dev/S7 and I've tried to mount it:

# udevadm control --reload-rules  # ls -l /dev/S7 lrwxrwxrwx. 1 root root 15 10-20 15:03 /dev/S7 -> bus/usb/003/075  # ls -l /dev/libmtp-3-1 lrwxrwxrwx. 1 root root 15 10-20 15:03 /dev/libmtp-3-1 -> bus/usb/003/075  # simple-mtpfs /dev/S7 /media/s7 

And still without any result. Mounting doesn't give and errors, but the directory where I about to mount is still empty.

The details about my setup:

# uname -r 4.7.7-200.fc24.x86_64  # rpm -qa | grep mtp simple-mtpfs-0.2-6.fc24.x86_64 libmtp-1.1.11-1.fc24.x86_64 gvfs-mtp-1.28.3-1.fc24.x86_64  # rpm -qa | grep fuse fuse-libs-2.9.7-1.fc24.x86_64 glusterfs-fuse-3.8.4-1.fc24.x86_64 fuse-2.9.7-1.fc24.x86_64 gvfs-fuse-1.28.3-1.fc24.x86_64 

Under Windows I can plug the phone and I see its whole content (the same as in Nautilius), but not as ordinary USB Mass Storage (drive with a letter assigned).

I've also tried to enable Developer Options and set the USB Debugging Mode and ... nothing.

Thank you in advance for your help.

I had a similar problem using jmtpfs. The "solution" I found was to unmount/remount the device after allowing the connection on the phone following the first mount. This is not elegant, but maybe somebody with a better understanding of how Android handles this aspect of MTP permission can provide a better answer based on this answer (if so, please ping me in the process!).

EDIT: I just tried something else... after plugging in the phone, from the pulldown notifications list selecting the one about "connecting via usb" gives a set of choices; explicitly selecting the MTP option, then mounting, works normally.
