#272 Nokia 6.1: new device report(VID=2e04 and PID=c026) is UNKNOWN in libmtp v1.1.13

[Anonymous]

Hi, thought I'd report this.

jmtpfs -l
Device 0 (VID=2e04 and PID=c026) is UNKNOWN in libmtp v1.1.13.
Please report this VID/PID and the device model to the libmtp development team
Available devices (busLocation, devNum, productId, vendorId, product, vendor):
1, 8, 0xc026, 0x2e04, UNKNOWN, UNKNOWN

The device is Nokia 6.1, also known as "Nokia 6 2018".

On KDE neon,
uname -a
Linux yarr-504-OUS 4.15.0-42-generic #45-Ubuntu SMP Thu Nov 15 19:32:57 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

I get
The file or folder udi=/org/kde/solid/udev/sys/devices/pci0000:00/0000:00:1a.7/usb1/1-1/ does not exist.
so can't say if it works (apparently, a known KDE/kernel bug in since kernel 4.14, https://bugs.kde.org/show_bug.cgi?id=387454)
The device creates a CDROM, which seems to work, but not the desired "USB File Transfer mode".

it is now listed in 1.1.16 release.
usually as soon as you umount the device will reset to the mtp state, or it could be configurable

The same for Nokia 7 Plus:

jmtpfs -l
Device 0 (VID=2e04 and PID=c025) is UNKNOWN in libmtp v1.1.13.
Please report this VID/PID and the device model to the libmtp development team
Available devices (busLocation, devNum, productId, vendorId, product, vendor):
1, 54, 0xc025, 0x2e04, UNKNOWN, UNKNOWN

I'm sorry I don't have technical knowledge i just copied the command. The phone is running the newest updated stock Android 9, One UI. I'm on Kubuntu 18.04.1. Right now when I connect the phone one of the "Open in Browser" options of Dolphin will work and show the internal storage of the phone. This wasn't possible before but I don't know what I did to get it working. Looking at my shell history, I only ran the commands
mtpfs
mtp-reset
sudo mtp-detect
and (tried to?) install Android file transfer from this repository https://github.com/whoozle/android-file-transfer-linux
jmtpfs -l now shows:
Device 0 (VID=2e04 and PID=c025) is a Nokia 6.
Available devices (busLocation, devNum, productId, vendorId, product, vendor):
1, 5, 0xc025, 0x2e04, 6, Nokia

It's possible to open and view files, but if I modify anything and try to save, a "mtp crashed unexpectedly" error message will show. I'm not sure, maybe this is expected behaviour?
The appearance in Dolphin is highly inconsistent, there are random crashes, not-working device options etc., but at least I have a semi-usable one way connection, and I don't think it's your problem anymore :)
