There is example PIC firmware for WinUSB here:

The examples Microchip provides are also a good starting point.

In winusb_cs_30 used ProductID = "1518";
In last PIC firmware (device-winusb_lvr.zip).
Used  ProductID 0х150C
I think there is a newer version of the firmware.
I want to work with isochronous transfers, but...

I found a bug in my code. USB_HANDSHAKE_DISABLED in ISO
   

Code: [Select]

//Enable the application data endpoint(s)
    USBEnableEndpoint(USBGEN_BULK_EP_NUM,USB_OUT_ENABLED|USB_IN_ENABLED|USB_HANDSHAKE_ENABLED|USB_DISALLOW_SETUP);
    USBEnableEndpoint(USBGEN_INTERRUPT_EP_NUM,USB_OUT_ENABLED|USB_IN_ENABLED|USB_HANDSHAKE_ENABLED|USB_DISALLOW_SETUP);
    USBEnableEndpoint(USBGEN_ISO_EP_NUM,USB_OUT_ENABLED|USB_IN_ENABLED|USB_HANDSHAKE_DISABLED|USB_DISALLOW_SETUP);

Of course you can change the Vendor ID and Product ID to whatever values you need.
