>Description:

"usbd_find_desc()" was put into the wrong file. The function belongs together 
with "usbd_find_edesc()" and "usbd_find_idesc()" and should take 
"usb_config_descriptor_t *" as argument.

>How-To-Repeat:

>Fix:

const usb_descriptor_t *usb_find_desc(usbd_device_handle dev, int type,
                                      int subtype);
#define USBD_SUBTYPE_ANY (~0) /* XXX mixing signed and unsigned types is not 
good */

changed into:

usb_descriptor_t *usb_find_desc(usb_config_descriptor_t *, int type,
                                      int subtype);
#define USBD_SUBTYPE_ANY (-1)

Usage: "usb_find_desc(usbd_get_config_descriptor(udev), ... );"
