3 Programming Interface CUsbIo::GetDeviceDescriptor Get the device descriptor from the device. Definition DWORD GetDeviceDescriptor( USB_DEVICE_DESCRIPTOR* Desc ); Parameter Desc Pointer to a caller-provided variable that receives the requested descriptor. Return Value The function returns 0 if successful, an USBIO error code otherwise. Comments GetDeviceDescriptor calls CUsbIo::GetDescriptor to retrieve the descriptor. Thus, for detailed information see also CUsbIo::GetDescriptor. The device must have been opened before this function is called. See Also CUsbIo::Open (page 28) CUsbIo::GetDescriptor (page 44) CUsbIo::GetConfigurationDescriptor (page 47) CUsbIo::GetStringDescriptor (page 49) 46 USBIO Driver for Windows CE
CUsbIo::GetConfigurationDescriptor Get a configuration descriptor from the device. Definition DWORD GetConfigurationDescriptor( USB_CONFIGURATION_DESCRIPTOR* Desc, DWORD& ByteCount, UCHAR Index = 0 ); Parameters 3 Programming Interface Desc Pointer to a caller-provided buffer that receives the requested descriptor. Note that the size of the configuration descriptor depends on the USB device. See also the comments below. ByteCount When the function is called ByteCount specifies the size, in bytes, of the buffer pointed to by Desc. After the function successfully returned ByteCount contains the number of valid bytes returned in the buffer. Index The index of the descriptor to request. Return Value The function returns 0 if successful, an USBIO error code otherwise. Comments GetConfigurationDescriptor calls CUsbIo::GetDescriptor to retrieve the descriptor. Thus, for detailed information see also CUsbIo::GetDescriptor. If the total size of the configuration descriptor is not known it can be retrieved in a two step process. With a first call to this function the fixed part of the descriptor which is defined by USB_CONFIGURATION_DESCRIPTOR is retrieved. The total size of the descriptor is indicated by the wTotalLength field of the structure. In a second step a buffer of the required size can be allocated and the complete descriptor can be retrieved with another call to this function. The device must have been opened before this function is called. See Also CUsbIo::Open (page 28) USBIO Driver for Windows CE 47
