SUDPTR
Can the USB core tell whether or not SUDPTR is pointing to a descriptor.If SUDPTR is pointing to vendor-specific information (instead of a USB defined descriptor) the second case stated in the TRM as follows
"The USB core transfers the lesser of (a) the bytes requested in the SETUP packet, and (b) the bytes in the length field pointed to by the SUDPTR"
is not applicable. How is this implemented? Also how is the entire configuration descriptor (with interface, endpoint descriptors) sent within one request if the SUDPTR is pointing to the configuration descriptor and the first byte in the descriptor states only 9 bytes.
