#274 Support for LeEco Le 2

[Marinos Trantalides]

I have the Android 6.1 smartphone "LeEco Le 2" and my desktop system runs Netrunner Rolling 18.1 Linux (a variant of Arch, 64-bit), sporting libmtp v1.1.15-1. Connected the LeEco Le 2 via MTP. However, when attempting to open the device (listed as "Android" in the stock Dolphin file manager), it fails with the message:
"The file or folder udi=/org/kde/solid/udev/sys/devices/pci0000:00/0000:00:14.0/usb1/1-9/ does not exist"
I also tried to open the device using gmtp but it would just keep on trying to open it without result.

(as a side note, MTP connection of this smartphone to a Windows 10 machine works OK, so, I suppose, we can rule out the possibility that the device is defective.)

I'm not really sure if the above error message is indeed libmtp-related or if it is due to other factors.

However here are the relevant diagnostics:

The device is found as follows by mtpfs --version:

EDIT: Tried the very same phone (LeEco Le 2, X526, 3Gb/64Gb) with the live CD of MX-Linux v17.1 (it's a systemd-free Debian variant, sporting libmtp 1.1.13-1) and the phone was mounted via MTP without any problem. Thus the problem seems to be unrelated to libmtp itself.

[Marinos Trantalides]

EDIT2: It seems this was a bug related to the combination of KDE with  Dolphin file manager(appeared in kernel 4.14, and, as per reports, still exists with kernel 4.18). It's all described here: https://bugs.kde.org/show_bug.cgi?id=387454

I solved it by following the steps suggested in comment #25 by Stefan Wezel, namely:

1. Copied the file /lib64/udev/rules.d/69-libmtp.rules to /etc/udev/rules.d

2. Edited the copied file /etc/udev/rules.d/69-libmtp.rules
        and changed (near the top) the line that read:
              ACTION!="add", GOTO="libmtp_rules_end"
          to:
              ACTION!="bind", ACTION!="add" GOTO="libmtp_rules_end"

3. Refreshed the udev rules (by running "# udevadm control --reload-rules && udevadm trigger"

After that, the phone was mounted without any problem with MTP

I'm not sure how to go about this ticket, perhaps the owner would care to remove it altogether now that it's crystal-clear that this was not an issue with libmtp.

i have added both the ID and also a udev rules patch to git. thanks!
