Hi 'bigcat',
It might be worth going back into the debug configurations, deleting the reference to the DSTREAM (USB:0000706), and browsing for it again. Does that help?
If not, I also recommend checking that you have the latest firmware installed (go to Window -> Show View -> Debug Hardware Firmware Installer).
