    Exclamation No power to USB attached device

    I have a Samsung Galaxy tab 2 7.0. I have the USB adapter and am using the adapter to connect a USB bar code scanner to. The scanner worked just fine since I have had the tablet (about 2 months) then the battery died and now the tablet will no longer power the scanner when attached via the USB connector. When I connect the USB adapter with the scanner plugged in I can see on the top of the screen the USB symbol and it says "USB connector connected" but I get no power to the scanner.

    I'm not sure what happened as this was working. Any info and assistance is greatly appreciated.

    I have a couple adapters that are called OTG ADAPTERs and they supply power to a keyboard or mouse. One is a short pigtail with Samsung 30 pin on one end and a USB on the other end. The other is about an inch square and plugs into the 30 pin and provides a micro usb outlet! I have used them since the last software upgrade so I know that is not the problem! Be sure your adapter is an OTG adapter!
