All previously connected keyboards and mice have run at all.
I have this adapter more than a month in use and the micro-USB plug to date is still sitting firmly.
Something other adapters I have now already purchased often was a shortcoming.
The adjusted image info has encouraged me to believe you could load the tablet on the Micro-USB port on the hub.
So, unfortunately, does not work; not USB-Standard so unfortunately just wishful thinking.
But !!
About the MicroUSB jack and the power supply of the tablets we transformed the whole into a USB Powered Hub.
One thus feeds the other devices on the hub, which this does not literally "empty eyes" the tablet battery.
A brilliant idea.
External hard drives or USB sticks I have not tested.
