Requirement for driver depends on the application that you are dealing with, see http://msdn.microsoft.com/en-us/library/windows/hardware/ff538853(v=vs.85).aspx for system supplied USB drivers. We have two application notes explaining application development in VC and VC# please go through these links http://www.cypress.com/?docID=28357 and http://www.cypress.com/?docID=27752.
I am trying to use the USB Suite. Which is the best forum for asking questions? Thanks Nick
