For me, this bug (if it's one bug we're talking about) was caused, or
exposed, by a recent dist-upgrade to testing. I have a Motorola Xoom
that I mount on my Debian wheezy box with:
mtpfs -o allow_other /media/android
(run as root). This has worked with no problems since I got the Xoom
about a month ago. In particular it was working on Friday evening
January 31st. But then:
Start-Date: 2013-02-01 00:01:06

As soon as the upgrade completed, I was unable to mount the tablet or
communicate with it at all.
% mtpfs -o allow_other /media/android

Device 0 (VID=22b8 and PID=70a8) is a Motorola Xoom (ID 1).

fuse: bad mount point `/media/android': Transport endpoint is not connected
and:
cd /media/android
bash: cd: /media/android: Transport endpoint is not connected
and the /media/android directory is listed as:
d????????? ? ? ? ? ? android
`adb devices' shows no devices attached and `adb shell' reports:
error: device not found (fusermount -u /dev/android returns the
directory listing to normal, as reported by another user above).
mtab, however, does list the device as mounted:
mtpfs /media/android fuse.mtpfs
rw,nosuid,nodev,relatime,user_id=0,group_id=0,allow_other 0 0
Among the packages upgraded, presumably mtpfs is the likely
culprit. And presumably the problem was caused by whatever is
different between version 0.9-3+b1 and version 1.1-4. Looking at the
changelog, the only likely possibilities seemed to be a dependency on
fuse rather than on fuse-utils, or else the move to a new upstream
version.
I tried purging fuse-utils but that made no difference.
I tried to downgrade to mtpfs 0.9-3 0 in stable, but apt wanted to
remove grub in doing that, so ....
Installing libmtp9 from the experimental repository made no difference.
I hope this is helpful.
