    The Bob needs a 5v connection from the PC. There are terminals to take the PC side of the power and a USB connector also. If you do not connect up 5v from the PC the opto couplers will not work properly.

    I can't see that connection on your photos.

    Here's a link to the Bob manual in my dropbox https://www.dropbox.com/s/v1fha65o2p...rd-EN.pdf?dl=0 Just in case you haven't got the document.

    Cheers !
