Hey guys,

I asked the other day if about this being possible, and turned out it already is!

I´m a noob, so I´ve just basically tried a little bit. All I did was:

1) Rooted my Xoom 2 10.1" Wifi following the Root Method by Dan Rosenberg

2) Installed "Drive Mount" from the Market (USB Mass Storage Watcher did not work for me)

3) Plugged my USB OTG adapter (http://www.amazon.co.uk/gp/product/B006R0XOLO/ref=oh_o01_s00_i00_details) to my HD IN THE FOLLOWING ORDER: adapter to HD, then both to the Xoom (I was getting constant freezes because I was plugging my HD to the adapter, once the adapter was already connected to the Xoom).

4) With Drive Mount opened, I mounted my old, NTFS, already partitioned, external HD, and it reads it fine!

Not only that, it even gave me enough juice to connect an old Conceptronic USB hub, then my external HD, then a 8 GB USB pen simultaneously, then move a 700 MB movie to and from the USB pen, without problems. I´ve even been able to watch a 4 GB movie from it!

More importantly for me, this actually makes the device capable of making copies on the go, and hopefully, replace the USB pen with a USB card reader, and download photos and movies from you camera to a HD, when you´re on the go. That´s great for me!

Like I said, I´m just a noob, so the only issue is that I have no idea if the Xoom´s battery could be "damaged", or its life expectancy seriously shortened, by connecting that many devices simultaneously. I´d appreciate if you guys could clarify this for me.

Enjoy!

No, as it's a near-certainty (anything else is amateur hour) that Moto installed current-limiting USB "VBus" regulators on the line you're drawing power from (limiting it to 1/2 Amp).

Thx for number 3. When i plug the adapter first to the tablet and then hard drive to adapter , touch screen stops respond (the tablet don't freeze but you can do anything ). I couldn't understand why sometimes worked and some didn't. Strange bug.

I have the exact same bug on my Xoom 2 Media Edition, also rooted.
When I plugin the USB OTG Adapter first in the Xoom and then a USB Stick in the Adapter the whole touchscreen is turned off, you can only force reboot with the back site hardware keys.

If i plugin the drive to the OTG and then the whole thing in my Xoom all is working great.

Have to try this with a Hub and two drives, would be awesome to save my Raw Files during Holiday.

Hope Moto fixes this bug, because sometimes i forget....:eek:
