Re: ReadPipeT0 always wrong!

Thank you  for your reply!
Yes, my driver doesn't based on CCID. Now it can be used,
if my ppc first start. But only there are problems when I restart pcsc service.
The ReadPipeTo has wrong messege.

Hi, I'm developing the USB dirver for my SmartCard Reader for Mac OS?10.4.

Is your smart card reader compliant with the USB CCID spec? If so, Mac OS X already has a CCID class driver and you shouldn't need to write your own.

If your reader isn't CCID compliant and you are able to influence its design, you should strongly consider making the reader a CCID device.
