Public bug reported:
I am unable to mount the filesystems on my HTC One m8 phone. It is an
Android 4.x device, which only supports the Media Transfer Protocol for
transferring files between the phone and a connected PC. USB Mass
Storage is not supported. My phone is the variant sold by T-Mobile USA.
When I use the "mtp-detect" program to connect, this message is printed
at the begininng of the output:
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

...so I am reporting this against libmtp, but there may be other related
packages that are affected. At one point, I saw a gvfs error message.
This might be considered related to bug #1314556, although I suspect
that many devices will run into problems when they are new.
Linux in general needs very robust MTP support that is as forward-
compatible with new hardware as possible, especially now that newer
handsets no longer support the old USB Mass Storage method of
transferring files. It is not desirable to have new devices be unusable
when they are released and have to wait 6 to 12 months for a new Ubuntu
release before they start working, especially since many smartphones are
only sold for a year or two before being replaced by new models.
I use the XFCE desktop environment. I am able to get an "Android Phone" icon to
appear on my desktop, but when I initially clicked on it, an error would occur
and I'd be unable to mount the device. After enabling USB Debugging on the
phone (which is a hidden feature on this particular device, requiring using a
simple "Easter egg" to expose the setting), I began to be able to double-click
the "Android Phone" icon and then get a window with one icon for "Internal
storage" and another for "SD card". However, clicking on either of those
results in an error dialog with the message:
Unhandled error message: Unable to open MTP device '[usb:005,011]'
