Cardreader without numpad errors #19

Closed exolyte closed 5 months ago

exolyte commented 6 months ago

I'm using a ACS ACR38U 00 00 cardreader and was getting the following error when trying to run commands that require pin authentication: stderr output from native app com.connective.signer: Failed to control Feature not supported.

I tracked the issue down to this function call features = self._connection.control(smartcard.scard.SCARD_CTL_CODE(3400), []) which is part of the smartcard library if I understand correctly.

I commented out self.__get_reader_features() and L511-530 and the commands worked just fine.

Since it started working I didn't really dig any deeper and I'm not sure if there's anything to fix for you, but I figured this might help some people.

Thanks for your report and glad to see you were able to work around the issue.

The part you commented is the test to detect if there is a numeric keypad on your cardreader or not. Your modification always shows the keypad on screen, which is a great default if the capabilities cannot be detected.

I'll modify it that way, but since it is not urgent it may take some time.

I added extra error handling but I didn't disable lines 511-530, that code will be skipped if the detection flags are all set to False.
