Hi, I am trying to play around with the USBSample that is provided when you download the JDE. I see that the initial project was built for VC++ 6. Upon opening in VS 2008 and trying to compile (after it does project conversion) I get a plethora of link errors. Any ideas what I need to do to get this project to compile correctly? Thanks in advance!

I had the exact same issue.

The solution was to go in to the project configuration, and it turns out a bunch of libraries were set to be 'excluded' by the conversion wizard. Simply removing everything from the exclusion list allowed me to compile without error.

I appologize but I was hoping you could give me some further details on what I need to do in order to get this to work in Visual Studio 2008. Any help that you can give me would be greatly appreciated.
