Chapter 10: LPC11U3x/2x/1x USB on-chip drivers
10.5.17 _USB_CORE_DESCS_T
USB descriptors data structure.
10.5.18 _USB_DEVICE_QUALIFIER_DESCRIPTOR
10.5.19 _USB_DFU_FUNC_DESCRIPTOR
Table 191. _USB_CORE_DESCS_T class structure
Member Description
device_desc
uint8_t * _USB_CORE_DESCS_T::device_desc
Pointer to USB device descriptor
string_desc
uint8_t * _USB_CORE_DESCS_T::string_desc
Pointer to array of USB string descriptors
full_speed_desc
uint8_t * _USB_CORE_DESCS_T::full_speed_desc
Pointer to USB device configuration descriptor when device is operating in full speed mode.
high_speed_desc
uint8_t * _USB_CORE_DESCS_T::high_speed_desc
Pointer to USB device configuration descriptor when device is operating in high speed mode.
For full-speed only implementation this pointer should be same as full_speed_desc.
device_qualifier
uint8_t * _USB_CORE_DESCS_T::device_qualifier
Pointer to USB device qualifier descriptor. For full-speed only implementation this pointer
should be set to null (0).
