Detailed Description

This structure defines a USB host class driver interface, it is parsed to find a USB class driver once a USB device is enumerated.

Field Documentation

ui32InterfaceClass

uint32_t tUSBHostClassDriver::ui32InterfaceClass

The interface class that this device class driver supports.

pfnOpen

void*(* tUSBHostClassDriver::pfnOpen) (tUSBHostDevice *psDevice)

The function is called when this class of device has been detected.

pfnClose

void(* tUSBHostClassDriver::pfnClose) (void *pvInstance)

The function is called when the device, originally opened with a call to the pfnOpen function, is disconnected.

pfnIntHandler

void(* tUSBHostClassDriver::pfnIntHandler) (void *pvInstance)

This is the optional interrupt handler that will be called when an endpoint associated with this device instance generates an interrupt.
