Did the measurements the way you instructed. At first I got 1.8/0.0/1.8/1.8, so I cleaned the pins. After that I now always get 1.8/3.3/1.8/1.8. values are for the pins 6 and 5 from left to right as in this picture: http://www.pasteall.org/pic/show.php?id=63234 using the usb port as ground. Cleaning the pins on the tohkbd and connecting the toh does not change things, I still get the same error message and none of the keys work. Suggestions?
