[quote]rst you had to uninstall the old GHI SDK completely.
I tried the same thing and had the same issue, but after everything was all done, I had to manually go into the device manager and update the driver to the new GHI SDK folder before my computer would recognize it correctly (Windows 7 - 64-bit).
I also had to unplug from a USB host, right into the computer and everything worked fine.
I think my USB hub was not letting it read correctly. It might have not been the manual driver installation that fixed it, but this was the process I used in order for it to work.
Updated 2 pandas.

PS, after updating Firmware, plugged back into my USB Hub, and works good.[/quote]
Thanks for the tips, but…
I did completely uninstall the old SDK and install the new one. I updated the firmware to what was included in the new SDK, verified the version and even made some stick-on labels so I could keep track of which boards I have upgraded the firmware on Everything was fine. I had to remove my old references and re-add them so it would pick up the new versions.
I was able to run my old project just fine. The moment StartCDC_WithDebugging() was called is when the problems started. I unplugged the board several times, and I am not using a hub.
