$ lsusb | grep Pixel
Bus 004 Device 006: ID 18d1:4ee7 Google Inc. Nexus/Pixel Device (charging + debug)

I did check relevant faq entry, but device has correct group I'm also part of:

$ ls -lt /dev/bus/usb/004/
total 0
crw-rw----+ 1 root plugdev 189, 389 Nov 29 22:01 006

$ id | grep -Po '\d+\(plugdev\)'
46(plugdev)

Note bus directory is owned by root:root, is this OK?:

$ ls -lt /dev/bus/usb/
total 0
drwxr-xr-x 2 root root 120 Nov 29 22:20 004

Running android-file-transfer 4.2-2 on Debian testing. Also tried with Android_File_Transfer_For_Linux-9967dec-x86_64.AppImage from github releases. Android 11.

(charging + debug) may mean you have to explicitly enable "File Transfer (MTP)" on your phone (try tapping charging notification). MTP is not enabled by default anymore.

did it work? :)

did it work? :)

Can't test it atm - bricked the phone with acc

oh my, I'm so sorry about it. Feel free to reopen this if you revive your phone and the issue is still present

I have a similar issue. I just built your wonderful tool from source on macports (will update the port which is quite outdated and depending on osxfuse instead of macfuse). However, I cannot connect my phone : no MTP device found (from the UI or CLI). Complete output from the CLI:

It might be related to my phone configuration. It is a Oneplus 3 (Oneplus A3000 with android 9, OxygenOS 9.0.6). Note that adb devices lists it correclty as a device. I tried to explicitly allow MTP from the phone configuration. However, the option is not available, only the following are (I tried "File transfer" and "PTP". In Developer Options/USB Preferences:

• File Transfer
• USB tethering
• MIDI
• PTP
• No Data Transfer

Would you have some clues for me to investigate further? Likely related to the phone or to fuse? I can provide you with any needed information! Thanks a lot for your great work.
