Re: problems setting raspberry pi up with lapdock 500

Does anyone know what type of connector is used for the USB/HDMI connector internally? I'm going to try make a cable for it completely from scratch with a push button built in

Re: problems setting raspberry pi up with lapdock 500

I got my hands on that adapter, very interesting little thing. The HDMI is a straight pass through, but the USB connection has some weird stuff on it I managed to make a schematic of the board: http://i.imgur.com/a4jjHm4.png (note this may not be 100% correct.

Re: problems setting raspberry pi up with lapdock 500

I managed to find a dirt cheap Webtop connector, should be arriving this week. At this point this connector is everyone's last hope :/

It would certainly identify what the Motorola devices use to communicate, but it may not be very useful beyond that. Gonna need some VERY high quality images of the insides if you do get one

Re: problems setting raspberry pi up with lapdock 500

Does anyone have access to a Webtop Travel Adaptor? (http://www.amazon.com/Motorola-Travel-A ... 005J373HG/) if we can crack one of them open, it might tell us how the devices communicate with the phone

Re: problems setting raspberry pi up with lapdock 500
