The ultra debug board uses a different FTDI chip (vid:did 0403:6010), which has two ports. The SPI interface on this chip is hooked up to the second port, but the code indiscriminately uses the first port when trying to open the SPI channel, on all devices known to it. Adding a new field in the supported_devices table allows to keep default behavior, but use port B (the second port) when required. Also, fix printout formatting problem.
