Descriptor used for the whole device
Field Documentation
| uint8_t app_usbd_descriptor_device_t::bDeviceClass |
Device class code.
If 0, each interface specifies its own class information. 0xFF for vendor-specific.
| uint8_t app_usbd_descriptor_device_t::bDeviceProtocol |
Subclass code.
If 0, no specific protocol is defined on device basis. Each interface may define its own protocol then. If set to 0xFF, vendor-specific protocol is used.
| uint8_t app_usbd_descriptor_device_t::bDeviceSubClass |
Subclass code.
If bDevice Class is set to value other than 0xFF, all values here are reserved for assignment by USB-IF.
