Public bug reported:

Usually this device mounts with both internal and SD card storage
appearing in an "Android Phone" folder in nautilus. Sometimes this does
not work straight away.

During copying several megabytes of images, with the phone screen on and
unlocked, a message appears indicating an error copying. Most files are
copied, even though the progress bar seems to stop at around 30%. All
attempts to access the device in nautilus result in and empty set of
results where the files normally appear.

Removing then re-inserting the USB plug gives the message "Unable to
mount Android Phone Unable to open MTP device '[usb:002,008]'" in a pop-
up message.

mtp-detect reports:
Unable to open ~/.mtpz-data for reading, MTPZ disabled.libmtp version: 1.1.6

Listing raw device(s)
Device 0 (VID=0bb4 and PID=0f25) is UNKNOWN.
Please report this VID/PID and the device model to the libmtp development team

OK.

I have tried adding the following udev rule to resolve this:
$ cat /etc/udev/rules.d/69-libmtp.rules 
# HTC One M8
ATTR{idVendor}=="0bb4", ATTR{idProduct}=="0f25", SYMLINK+="libmtp-%k", MODE="660", GROUP="audio", ENV{ID_MTP_DEVICE}="1", ENV{ID_MEDIA_PLAYER}="1"

I've tried using a different USB port but this has no effect.

Eventually, after removing and re-inserting the USB cable and being
patient, it starts working again and it's possible to access the files
again, but the problem re-occurs very quickly.
