Get the table of supported LANGIDs for the given device
#include <sys/usbdi.h> usbd_string_descriptor_t *usbd_languages_descriptor( struct usbd_device *device, struct usbd_desc_node **node );

The usbd_languages_descriptor() function lets you obtain the table of supported language IDs for the device.
The usbd_string_descriptor_t structure looks like this:
typedef struct usbd_string_descriptor { uint8_t bLength; uint8_t bDescriptorType; uint16_t bString[1]; } usbd_string_descriptor_t;
A pointer usbd_string_descriptor_t on success, or NULL on error.
