I have been using libusb in visual studio to write console application capable of transferring data to CY8CKIT-050. My code works for Bulk and interrupt transfer i.e. I can send data from computer to PSOC and get it back as well. However, for isochronous transfer it gives LIBUSB_ERROR_NOT_SUPPORTED. I have searched on the internet and to my understanding libusb doesn't fully support isochronous mode of transfer. 

   

please help me If anyone knows a library with a sample code that can help me writing a code for isochronous transfer. I'm using windows 10 and visual studio 2013 to write a c/c++ console application to communicate with CY8CKIT-050 development kit.

Yeah. I have tried this. There are some unofficial patches available on GITHUB for libusb. But there feedback is not good and that is why they haven't added those patches to the libusb. That is why I was wondering if cypress has some sort of library which can help me.
