Most tablets only have a single Micro USB port that is used to charge the tablet, or can be used to plug in regular USB devices like a keyboard/mouse using USB OTG. I would like to charge/power my tablet AND be able to connect to USB devices at the same time.
Will an adapter like this be able to do that? If so, does the tablet need to support a certain protocol? Specifically, I'd like to know if anyone has succesfully used it on a Dell Venue 8 Pro or other windows 8.1 tablet.
Update: From Wikipedia, USB OTG can support the following
- A charger and either no device or an A-device that is not asserting VBUS (not providing power) are attached. The OTG device is allowed to charge and initiate SRP but not connect.
- A charger and an A-device that is asserting VBUS (is providing power) are attached. The OTG device is allowed to charge and connect but not initiate SRP.
- A charger and a B-device are attached. The OTG device is allowed to charge and enter host mode.
But this wording is very unclear, and the citation is broken. If "OTG Decice" is the tablet, and "B-device" is the peripheral, then the last point would seem to indicate that the tablet could charge and act as a USB host to the peripherals at the same time.
