I used CY7C68001 chip and ezusbdriver for my product.
At that time we jest supported 32bit OS system.
Now I have to support 64bit OS, and I downloaded Cypress Suite USB 3.4.2 .
My old project used Win32API, and I success to creatfile function using symbolic link.
Now I can't use DeviceIOControl because of header file.
I used ezusbsys.h file for deviceiocontrol.
There are some defines like "IOCTL_Ezusb_GET_PIPE_INFO", "IOCTL_Ezusb_GET_DEVICE_DESCRIPTOR"..etc,.
and I think cyioctl.h is the file waht is instead of ezusbsys.h.
However there are different defines. I don't know how to control USB IC using new driver on my old project.
If you have any idea for guiding me, please let me know.
