  UcsiUsbOperationRoleDfp = 0x1,
  UcsiUsbOperationRoleUfp = 0x2,
  UcsiUsbOperationRoleAcceptSwap = 0x4,
  UcsiUsbOperationRoleDfpAcceptSwap = 0x5,
  UcsiUsbOperationRoleUfpAcceptSwap = 0x6
} UCSI_USB_OPERATION_ROLE;

Constants

 
UcsiUsbOperationRoleDfp
Value: 0x1
The connector initiates swap to downstream-facing port (DFP), if not already operating in DFP mode.
