I have a LG-P930 cellphone with Gingerbread 2.3.5. This device has a micro-USB connector that shares pinout with HDMI. I bought a MHL adapter but it seems that the USB plug on this device is for power only.
I know that my question is not purely about Android but does someone know about a MHL adapter that would preserve the USB data connection? In other words, I would like to connect to my HDMI screen while communicating with the computer through USB.
