Loading script file to Cypress ezUSB fx2lp

Yusuf Sekman
Is that possible to use libusb drivers for loading script or program files into "cypress ezusb" USB controller device. When the script file is loaded into device. Device resets its usb controller and start enumeration with another PID. Can we do this by modifying libusb drivers?

You do not modified libusb drivers to do that. You use libusb-win32 driver and
then write a program based on libusb-win32 API to do that. There are quite
some examples on the Internet.

Eg: this one is quite complete, works under Linux and Windows.

Much simpler examples are here.
