Reader does not answer to GET DATA RATES command
If I use the parse tool from my CCID driver to get the supported clock list I get:
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.
