MTPFS 1.1 – Now supporting multiple storage areas

by

I am now the proud owner of an Asus Transformer tablet (not the prime) and so wanted to update mtpfs to work better with it.

The biggest change was to add support for multiple storage areas.  Now when you mount a MTP device which has internal storage and a MicroSD card (or similar) it shows up as two separate directories which you can access.

The download is available from mtpfs page

  2. When I mount an encrypted Android ICS (4.0.2) phone and try to browse the file system, I get a bunch of these errors:
    kernel: usb 1-8.2: usbfs: process 1619 (mtpfs) did not claim interface 0 before use

    I have not tried an unencrypted device, so I’m not sure if that’s the issue.

    [WORDPRESS HASHCASH] The poster sent us ‘0 which is not a hashcash value.

  5. Version 0.9 used to work, kinda-sorta on the Samsung Galaxy Tab2 7.0 as long as you use version 1.1.5 of libmtpfs. The way it worked was it did a sort of union mount of the internal memory and sdcard on top of each other and set the permissions to 777. This version, 1,1, doesn’t work at all.

    toybox:~$ mtpfs foo
    Error: Unable to open ~/.mtpz-data for reading.

    Device 0 (VID=04e8 and PID=6860) is a Samsung Galaxy models (MTP).

    toybox:~$ ls foo

    I think you should seriously look at doing some heavy code-borrowing from go-mtpfs and jmtpfs. Both of those work.

  6. hi,
    thanks for mtpfp.
    I install it on Debian Wheezy (with libmtp-dev fuse libmtp9 pkg-config libfuse-dev libglib2.0-dev libmad0-dev libid3tag0-dev packages), and when I do
    $mtpfs , with mtp enabled on my LG Optimus L5 I have this message :

    Listing raw device(s)
    Device 0 (VID=1004 and PID=631c) is UNKNOWN.
    Please report this VID/PID and the device model to the libmtp development team
    Found 1 device(s):

    Error 2: (Look this up in ptp.h for an explanation.)

    any idea ?
