Without this function the USB compliance test (USB 2.0 Command Verifier) will fail in the "Interface Descriptor Test" with this error message:
FAIL (1.2.51) A successful GetInterface request must return the alternate setting set by a prior call to SetInterface.
Lets add this function to read back the value so that the DFU device fully passes the USB compliance test.
