Detailed Description

MSC Bulk-Only command block wrapper (CBW)

Member Data Documentation

◆ CBWCB

uint8_t _usb_host_cbw::CBWCB[16]

The command block to be executed by the device

◆ CBWCBLength

uint8_t _usb_host_cbw::CBWCBLength

The valid length of the CBWCB in bytes. This defines the valid length of the command block. The only legal values are 1 through 16 (01h through 10h).

◆ CBWDataTransferLength

uint32_t _usb_host_cbw::CBWDataTransferLength

The number of bytes of data that the host expects to transfer on the Bulk-In or Bulk-Out endpoint during the execution of this command

◆ CBWFlags

uint8_t _usb_host_cbw::CBWFlags

Bit 7 Direction - the device shall ignore this bit if the dCBWDataTransferLength field is zero, otherwise: 0 = Data-Out from host to the device, 1 = Data-In from the device to the host. Bit 6 Obsolete. The host shall set this bit to zero. Bits 5..0 Reserved - the host shall set these bits to zero.

◆ CBWLun

uint8_t _usb_host_cbw::CBWLun

The device Logical Unit Number (LUN) to which the command block is being sent

◆ CBWSignature

uint32_t _usb_host_cbw::CBWSignature

Signature that helps identify this data packet as a CBW. The signature field shall contain the value 43425355h (little endian), indicating a CBW

◆ CBWTag

uint32_t _usb_host_cbw::CBWTag

A Command Block Tag sent by the host. The device shall echo the contents of this field back to the host in the dCSWTag field of the associated CSW
