Enumeration Type Documentation

enum app_usbd_msc_protocol_t

MSC protocol possible value.

Note

The USB Mass Storage Class Control/Bulk/Interrupt (CBI) Transport specification is approved for use only with full-speed floppy disk drives. CBI shall not be used in high-speed capable devices.

Enumerator
APP_USBD_MSC_PROTOCOL_CBI	Command/Bulk/Interrupt
APP_USBD_MSC_PROTOCOL_CBI_ALT	W/o command completion
APP_USBD_MSC_PROTOCOL_BULK	Bulk-only

enum app_usbd_msc_req_t

MSC USB requests nrf_drv_usbd_setup_t::bmRequestType.

Note

Requests are limited only to APP_USBD_MSC_PROTOCOL_BULK protocol type.

Enumerator
APP_USBD_MSC_REQ_BULK_RESET	Mass Storage Reset
