My tablet nexus 7 have only 1 usb charging port.
I need to use a usb barcode scanner and also charge the device at the same time
i have not bought any usb converter or hub yet to test.
want to know if this have been tested and worked before.
 
My self powered usb hub does not charge while the hub is attached. Kind of makes sense, no DC connection, no power drain.

Haven't tried a non powered hub. Seems that would work.

I'm using a non powered OTG cable.
