    Isn't a tab 8 about 8 years old?

    Also some chip reader/usb port devices do not mandshake nicely in
    every case.

    As old as I remember those being, that may have been back in the

    is as secure as it gets, eh?

    It is for USB. Devices are either controllers or targets (formerly
    known as masters and slaves.)

    Does anyone know of devices that can do both?

    It's sad that USB was not designed as a real bus.

    A true OTG device can do both. But implementing a true device is a different story.

    USB was a master/slave 'bus'. The master (host) was the sole source of electrical power to run your mouse, keyboard, speaker, etc.
    So, a master could charge a phone. The phone, on the other hand is
    a slave (and thus won't try to provide regulated power on the bus).

    OTG was the name of the change that made it possible to power a gizmo
    from a phone, and it ONLY worked with micro-USB connector (they had to use an extra pin).
    Maybe your Lenovo was not OTG-compatible, or maybe it has a bad extra pin. I've been
    able to use OTG-connect memory sticks with iPad and Android tablets, but there's some
    wierdness (takes a special app on the iPad, and reformatting the stick is verboten).

    What's the file system on the memory stick?

    I'd be happy to download and install it myself, though
    this isn't as easy as it could be. Tablet couldn't
    even see two .apk files in an APPS folder that I created
    using usb file transfers from PC. Apparently the file
    system partially mirrors itself without giving instructions
    on navigating on one side or the other - can't get there
    from here. Tap, Tap, Swipe, Swipe, Tap, Tap, TAP-TAP
    Bloody TAP.

    And what's this locating service that must be enabled
    before an app will run? Not just enabled, but set to
    High-Def (all com modes). And if it's so 'HighDef',
    then why does the tablet tell me that I'm currently
    located at the intersection of two parallel streets?
    . . . when I didn't even ask?

    That doesn't make sense. You can do any file transfer with a PC and slave Android.
    I prefer to transfer from PC anyway, even will another USB stick on the PC.
    Oh, it makes sense, all right. You can't install an application with 'file transfer'
    because you can't access the directory where apps reside. You can't even inspect
    the filesystem except within a walled-off area (try, for instance, to find a fonts
    folder, or a picture file from a text message).

    Maybe there's developer tools that can explore the walled garden...

    You can do it all with rooted device. The protection is for accidental messing up of files, just like a typical Linux system.

    By the way, why can't you install apps or transfer files with ADB (Android Debugger)? ADB will take care of all the details without rooting (by-passing security) the device. And if you must root it, be sure to turn off the cell radio, or your phone is
    wide open to Russa, China, Iran, N. Korea, etc. There are reasons for the phone's tight security.

    Yeah, one has to have a "fully jailbroke" phone to get access to
    those areas, but some carriers do not allow such 'behavior'.

    I have a phone I never used that had two sim card slots in it and
    Verizon would not put it on their plan or system. I was so pissed.
    It is for folks that travel to Europe a lot or Israel. No need to
    switch phones or have two or any of that nonsense. I still want to
    get it and see if ATT will let me use it. It is only about 5 years
    old now, but it was a top notch "Viewsonic" phine. I don't know if
    they are still is or ever got going in the cell phone world, but it
    was cool for its time.

    OK - I finally found a micro-usb 3 to USB adapter with
    the correct pin grounded (connection between ground and
    adjacent 'I/O' pin, NOT the center pin)

    With this usb pin connection, the TAB 8 reads memory
    sticks on the usb port without system setting adjustments.
    It just recognizes the connecting - flags a notice to
    the user and opens the drive when the notice is tapped
    (maybe tapped a few times - hard to tell with this screen).

    All the other micro-usb hardware I had was missing this
    connection. I asked Mohamed at the cell phone shop
    next door to keep an eye out for one. His supplier had
    just that - one adapter. Now it's mine. Nobody else
    can have it.

    I actually went through a couple of places checking to
    see if ANY of their micro-usb connectors or peripherals
    had this connection. (have socket with pin sensors
    attached) NADA.

    So when someone says it's USB OTG, measure it.

    Might be worth kludging the contact permanently if ever
    the TAB 8 is in the shop for battery, screen or other
    repairs.

    Yeah, well, finding files after transfer is another
    issue.

    Files and folders don't seem to show repeatable
    navigation - dependent on where listed and
    how approached in the GUI

    Isn't a tab 8 about 8 years old?

    Also some chip reader/usb port devices do not mandshake nicely in
    every case.

    As old as I remember those being, that may have been back in the
    virus on a stick days. So they put extra security in. No connection
    is as secure as it gets, eh?
