Well after further inspection that is one way to make it work but I don't think it's the proper way because HDMI doesn't work either
Using the factory charger cable with no extension cable did nothing different, it still doesn't work
Its very strange because my HDMI works great also. What mhl adapter are you using? Im using this for my S5 http://www.amazon.com/Demupai-Adapter-Samsung-Galaxy-Smartphone/dp/B00SGNZM88?ie=UTF8&psc=1&redirect=true&ref_=detailpage

I had my 8100 put in my new car the other day and had something like this happen..
Put the USB cable on the USB2 , pluged in the phone (that worked before in the old car) , and nothing happened
after some trial and error, I used a different USB cable and IT WORKED , I'm thinking the other one my have only allowed for charging, no data...
so try another cable ....
