We have now updated our own CANUSB driver DLL, sorted out 3 minor bugs and also made it available for a true Windows 7 64bit. If you plan to develop 32bit applications on Windows 7/64 you should still use the 32bit version of our DLL and run it as wow64. In this version we have also added interface to C# with separate C# DLL’s. You find the latest drivers at our download page.
