Thread: USB file transfer to Motorola Xoom

  1. #1

    Default USB file transfer to Motorola Xoom

    Hi there,

    I recently got a Xoom and have been loving it. However, I can't get USB file transfer to work. Apparently the devices is connected by mtp and I've got mtp-tools to use from the command line, but they're not able to mount the device or connect to it in any other way, although they recognize it. I've even fiddled around a bit in /etc/udev/rules.d according to the instructions in this thread:
    https://supportforums.motorola.com/t...45977?tstart=0

    Didn't do a thing, sadly, although I wasn't able to get gnomad to work - it kept on claiming it was missing dependencies, which it wasn't, as far as I could tell. I've got Ubuntu running on another computer, though, and installed gnomad on that. Also no dice, although I hadn't changed /etc/udev/rules.d on that computer.

    Anybody have any tips how I could get USB file transfer running? I'd be really happy if I could stop using FTP to transfer everything

    hi erget

    I wonder have you fixed that issue with xoom as I am expecting my one to be delivered

    What operating system is recognized when you connect xoom to opensuse?
    Have you tried cat /etc/filesystems and add new filesystem? Editing these file by adding new filesystems helped me when opensuse could see my pendrive but couldnt open it.

    Take a try and let me know how you fixed that?

    Good Luck

    Hi loand,

    No, sadly I haven't gotten it working yet. No answers on any forums either except for yours, I think I might be forum cursed

    How could I tell what operating system is being recognized when I connect by USB? As far as the file system is concerned, I believe it's FAT32 or something conventional, although I haven't been able to verify that... A lot of people have asked why Google chose MTP rather than normal USB storage and it apparently does have some advantages, but I haven't been able to get it to work so I'm still using my work's file server to transfer data

    To make a long story short, when I connect the USB cable from the Xoom to the PC, nothing is recognized. The Xoom doesn't do anything and SUSE doesn't pop up any kind of message saying that I've connected an external device like I'm used to.
    If I try to connect using mtp-tools, I can see that the Xoom is recognized, but it doesn't tell me much more. Here's the output of mtp-detect:
    Code:
    lee@linux-hr34:~> mtp-detect

    Don't know if that provides any additional information, but maybe it helps The device is great, if you manage to get USB transfer working for you I'd love to hear how

    hi erget, to bad to hear you didnt do it yet, but you will get it working all right!

    Linux is not like windows so we have to forget about windows popping out that new hardware is found
    I am beginner in linux and not a pro yet but I think if the device is not mounted or recognized by system you will not be able to transfer data with mtp, maybe you should try mounting that xoom

    I found something, check it and let me know if that works, I hope it will help

    Hi loand,

    Yeah, I've been using Linux for a while now and I love it, when I have to take care of somebody else's Windows computer it always seems a bit quirky to me by now, since we use SUSE only at work and I do at home too. Nonetheless, I had hoped that the system would recognize the Xoom like an external HD. Of course, due to the mtp thing that didn't happen, but it would be nice if I could mount it like in that guide.

    I tried out the link - thanks a bunch, by the way, I had stumbled over that one but was nervous to try it because they tell you right at the beginning to install mtpfs, which I couldn't find for openSUSE - and unfortunately still wasn't able to get everything running. Added the rules to /etc/udev/rules.d, made the directory /media/xoom, and changed fstab. The only things I wasn't able to do were:
    1. install mtpfs, see above
    2. edit /etc/fuse.conf, since it wasn't in /etc
    3. add my username after "fuse" in /etc/group, because /etc/group didn't have "fuse" in it

    Perhaps that's the problem? I think it's a little difficult with my limited knowledge of the differences between the SUSE and Ubuntu architectures to duplicate the process, but it was worth a try

    Hi,

    Is the xoom coming with android OS ? I have an android device, but I don't recall using mtp protocol to connect to it (I have an Archos Internet tablet).... hummmmm. Not sure though. Well, I don't have any problem to make it work with linux.

    I'll have to check that and tell you later.

    EDIT : ok, I recall. it uses something called the "msc" mode. I have to find what it is. I don,t know if you have this mode on the xoom. Fisrt thing to know if it is an android device.

    The xoom uses mtp which needs the mtpfs -o allow_other /{mount_point}.
    In tumbleweed command is included. I haven't tried yet with my xoom.
    I have used dropbox and bluetooth but need to try the mtpfs command it
    would be a lot faster.
    BTW, I've had the xoom since launch it almost replaces my laptop. Great device.

    Just tried it and it worked, as root run the mtpfs command and the xoom mounted. Now just need to
    figure out how to convert my linux journal pdf's to epub that work.

    hi dwellen, great to hear your xoom connects just fine with opensuse! I am waiting for my one to be delivered and cant wait
    by the chance can you exactly tell how you connect it and make it work with opensuse, please.


    Thanks
