I have 2 female to male USB Micro cables, which have been tested with an external power supply. Both work. I use a USB A to USB A cable to connect the USB ports, which also powers the PI when plugged into my Windows laptop. I use a 3 foot HDMI cable and 1 of 2 HDMI micro adaptera. The cable has tested good, no way to test the adapter. The Pi is a model B, made in China, which boots everytime except when hooked to the Lapdock.
The push to test on the Lapdock shows that the batteries are charged, but nothing happens when hooked to the Pi. No "Any" key or any other key either produces any reaction. Everything sits dark & dead.
Is there a specific key sequence required to launch the Lapdock?
