Indicates if the AOA interface's IN data pipe should use double banking.

uint8_t USB_ClassInfo_AOA_Host_t::DataINPipeNumber

Pipe number of the AOA interface's IN data pipe.

uint16_t USB_ClassInfo_AOA_Host_t::DataINPipeSize

Size in bytes of the AOA interface's IN data pipe.

bool USB_ClassInfo_AOA_Host_t::DataOUTPipeDoubleBank

Indicates if the AOA interface's OUT data pipe should use double banking.

uint8_t USB_ClassInfo_AOA_Host_t::DataOUTPipeNumber

Pipe number of the AOA interface's OUT data pipe.

uint16_t USB_ClassInfo_AOA_Host_t::DataOUTPipeSize

Size in bytes of the AOA interface's OUT data pipe.

char* USB_ClassInfo_AOA_Host_t::Description

Device description string.

uint8_t USB_ClassInfo_AOA_Host_t::InterfaceNumber

Interface index of the AOA interface within the attached device.

bool USB_ClassInfo_AOA_Host_t::IsActive

Indicates if the current interface instance is connected to an attached device, valid after AOA_Host_ConfigurePipes() is called and the Host state machine is in the Configured state.
