In version 6.0.0 of WinDriver we have modified the USB API in order to improve the support for this bus. The DriverWizard from versions 6.0.0 and 6.0.1 does not support code generation in Delphi (Pascal) for the new USB API. Due to a bug in the wizard from v6.0.0, the Delphi code generation option for USB was not disabled. This was fixed in v6.0.1 of WinDriver.
Note that the old USB API, for which you could generate Delphi code with older versions of WinDriver, is still supported by the driver of the newer versions, for backward compatibility.
Beginning with v6.0.2 of WinDriver, DriverWizard can be used to generate Delphi code that utilizes the new USB API.
