Do I need to install any driver for CP2615 on Windows?
CP2615 USB digital audio bridge is a composite USB device that provides three USB interfaces:
1. USB Audio Class 1.0 to I2S digital audio bridge
2. USB HID Class consumer control device for volume and mute synchronization
3. Vendor specific USB serial data bridge using CP2615 I/O Protocol
The USB HID and digital audio interfaces are standard class implementations and natively supported by most operating systems, no custom driver needed.
The CP2615 serial I/O USB interface uses bulk transfers, and WinUSB driver is required for Windows platform. However, some user may observe one of CP2615 interface cannot enumerate successfully on Windows 7 which the WinUSB driver has not been installed properly. In this situation, you need to install the WinUSB driver by yourself if you want to use this interface. For more information on how to install the WinUSB driver, please see here.
Below is the CP2615 device viewing in Device Manager on Windows 7 with WinUSB driver installation.
