I'm a newbie programming a FX2 device using the standard driver on Windows Vista.  I'm having problems (sometimes) connecting to the device (CreateFile() returns -1) and then call GetLastError() to deterine the error condition.


Unfortunately, I have not been able to locate the list of software driver error codes and their meaning.  Where are these defined (which document) in the development kit or somewhere on the web site?


Thanks, R
