Linux with Android MTP

[Shlomo Solomon]

I have the same problem on Mageia3 with a new Galaxy phone. I've read
that MTP is not reliably supported.

There is a partial solutions if your phone is rooted (although I
haven't tried it yet). Look at USB Mass Storage Enabler:

Aside from needing a rooted phone, this app only solves the problem of
accessing the external SD card - not internal memory. But that may be
enough. YMMV.

I'll probably also go for a wireless solution as Amichai suggested. I
mainly connected my Galaxy S1 phone over USB to do a complete backup
using rsync. I don't know if the wireless solutions will do for that. I
know there are apps that put an ftp server on the phone, so I guess
I'll just have to re-write my backup script to do rsync over ftp or
something.
