I have a Samsung Galaxy 10.1, running Android 3.2, which I've rooted.

When I plug it in by USB to my Ubuntu computer, it looks like this:

enter image description here

There's about 24 or so directories, all numbered as shown in the image. As far as I can tell, they don't correspond to any directories actually on the device, and I can neither find any files I think should be on the device or transfer any files to the device. (To be accurate: I can copy files to one of the weirdly numbered directories, but then I can't find them if I try to look for them from the tablet interface.)

What's going on, and, more importantly, how do I get a normal connection to my tablet so I can transfer files back and forth?

Update 1: I have learned this is probably "MTP mode". I can't seem to find any option to disable or change it.

Update 2: I have tried turning "USB debugging" both on and off, and neither way seems to make a difference.

Update 3: I've asked about this issue also on the Ubuntu SE site, in case part of my problem is on the Ubuntu side.

Update 4: Here's another error message I get if I try to use mtpfs to connect to the Android device:

  • Voting to close as this has been rendered moot by upgrading the tablet to Android 4. – Questioner Dec 3 '12 at 7:01

It seems that you're connecting the tab in Media Player (MTP) mode. Try switching it to Camera mode, it usually gives better results. If I remember correctly, this option can be found in Settings -> Storage -> Menu button (top right) -> USB computer connection.

  • Thank you for responding. However, there is no menu button at all under storage. There's just a bar graph showing me the device's storage memory usage. And I might be blind to the obvious, but I can't find any "USB Connection mode" option anywhere in the settings interface. – Questioner Apr 12 '12 at 10:42
  • Hmm, I was almost sure it was there. Now I'm running ICS so I can't check. Then your best bet would be to try gMtp, here's some instructions: forum.xda-developers.com/… – onik Apr 12 '12 at 10:50
  • Hey, can you find the menu Settings -> Wireless and networks -> USB Settings? This might solve your problem. – onik Apr 12 '12 at 12:11
  • There's no Settings -> Wireless and networks -> USB Settings either, I'm afraid. The only USB setting that I have found anywhere in the settings is Applications->Development->USB debugging. As mentioned in the question, it has no impact on this issue. – Questioner Apr 12 '12 at 13:40
  • Also, I tried to install gmtp as you recommended in a comment above, and I got through the whole process, but when I actually attempt to connect to my device through the gmtp interface, it hangs. – Questioner Apr 12 '12 at 13:50

Most likely hidden directories used by Android to store hidden data, that are shown/visible when you connect it to your computer.

Try using root explorer on your tablet to see the directories.
