    My rooted device was connecting to my DSLR Camera (Olympus E510) yesterday via USB OTG cable, but stopped. Now when connecting the gallery app opens to a black screen and locks up. The camera is not at fault because it connects to other devices just fine. I think I need a Terminal Wiz to tell me how to reset the USB settings or something on the android device.

    My camera has 4 settings to use to connect to a PC/Device, Storage mode, MTP mode, Print mode, and easy print mode. What would normally happen is I would put my camera in MTP Mode and plug it in my android device, gallery would open with all the photos on the devices memory card, and I would be able to view the photos and select ones to import. It worked fine yesterday, But now when connecting via USB in MTP mode the gallery app opens and then either sits there on a black screen, or it loads gray squares where the albums normally display. if I put it in storage mode android tries to mount the XD card, then reports that it has an unsupported file system (it is formatted as FAT)

    I have tried:
    • Doing a Data wipe, cache wipe, and delvik cache wipe.
      Flashing a different rom AOKP
      Re-formatting the camera memory card.

    Please help as I really need to have this functionality.

    I know it seems silly but check on the Nexus

    Settings>storage>Menu [three dots]> Usb

    is it set to connect as MTP or PTP.

    Thanks for the reply, I'll try that, in a little bit can't get to the camera until lunch, I unrooted the tablet and did a factory reset and the problem is still present, I am able to connect to it through USB from my computer VIA Fast boot, but I did just notice the tablet is not connecting to my PC via MTP, the tablet displays "Connected as Media Device" but is not showing up in my PC, when connecting as PTP, it opens a folder on the PC.

    I have also tried changing USB debugging on and off, but that didn't make a difference.

    [EDIT] I was able to get it to connect to my PC as an MTP Device, That problem was that windows was trying to load the ADB Drivers, I removed them and that part is working now.

    [Edit] I am wondering, what information is stored on android and where when a USB device is plugged into it? Examples being drivers or USB profiles for the device plugged in, I think what might be going on is the driver is currupted and needs to be deleted from the android device, but the factory rest did not do the job.
