Bug #4777

Reader does not answer to GET DATA RATES command

Spec Reference:
CCID v1.1 chapter '5.3.3 GET_DATA_RATES' page 24

Description

If I use the parse tool from my CCID driver to get the supported clock list I get:
https://ccid.apdu.fr/#CCID_compliant

bNumDataRatesSupported: 0 (will use whatever is returned)
   IFD does not support GET_DATA_RATES request: LIBUSB_ERROR_TIMEOUT

Since the value of bNumDataRatesSupported is 0 an empty list as answer would be perfect instead of a timeout.

The CCID spec says: "A CCID with bNumDataRatesSupported equal to 00h does not have to support this request." so the reader is stil compliant to the CICD specification. But an answer would be fine.
