does IOCTL calls to CyUSB need to be synced?

Hello,

I use direct access to CyUSB driver via IOCTL interface from different applications/threads at the same time. Do I need to manually synchronize access to driver using named mutex for example from different threads, or Windows/driver will handle such possible simultaneous calls correctly by itself? I use Windows 7.

Best regards, Arturas

 Hi,

         Yes, Windows kernal will handle it.

Thanks,
