struct | USB_Descriptor_Configuration_t |
USB Device descriptor structure for Mass Storage Device Type define for the device configuration descriptor structure. This must be defined in the application code, as the configuration descriptor contains several sub-descriptors which vary between devices, and which describe the device's usage to the host.

uint16_t CALLBACK_USB_GetDescriptor | ( | const uint16_t | wValue, |
const uint8_t | wIndex, | ||
const void **const | DescriptorAddress | ||
) |
USB Get descriptor callback function.
wValue | : Descriptor type |
wIndex | : Index of the descriptor |
DescriptorAddress | : Address of the requested descriptor |
This function is called by the library when in device mode, and must be overridden (see library "USB Descriptors" documentation) by the application code so that the address and size of a requested descriptor can be given to the USB library. When the device receives a Get Descriptor request on the control endpoint, this function is called so that the descriptor details can be passed back and the appropriate descriptor sent back to the USB host.
