3.6.2.1.1 USB

USB can enumerate in two interfaces, either CDC or CAPBridge. The descriptors are stored in two different files and depend on the 4-way switch status: switch mode 0-12 for CDC and CAP Bridge select switch mode 14 (refer to Mode Selection table for more information).

File usb_device_init_data_cdc.c contains the descriptors for CDC Interface and file usb_device_init_data_capBridge contains the descriptor details for CAP Bridge interface.

Use the standard Harmony 3 USB CDC drivers for CDC configuration and USB enumeration. For CapBridge configuration, vendor class is used and vendor/product IDs are hardcoded to match the CAP1xxx PC software. The code related to USB CDC and CAPBridge is present in usbApp.c file.
