DLP LightCrafter 4500 can't be recognized when connected to PandaBoard 4500

DLP LightCrafter 4500 can't be recognized when connected to PandaBoard 4500. The OS can't recognize even an unknown USB device. However, everything is fine if PandaBoard 4500 is removed from LightCrafter.

BTW, the LightCrafter 4500 GUI always turns into 'no responding', when a HDMI cable is plugged in.

I believe you are running the software on the PandaBoard that enables various IO configuration on board. If so, the PandaBoard boot up could block the USB enumeration for the external USB port on the LightCrafter EVM. So, if PandaBoard is connected to LightCrafter 4500 via USB as host-client setup then the external USB connection won't work.

Similarly the RGB 24bit signals would be driven by PandaBoard not via external HDMI port.
