Re: ReadPipeT0 always wrong!

There is another problem about my driver.

When the ppc wakes up from hibernation mode, there are the same wrong messeges

on my terminal, I think it is the same problem for my previous instance. The wrong messeges follow:

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.

any advice, Thax

You haven't provided nearly enough detail for anyone to give you any specific advice. The best general advice would be to use a USB bus analyzer to see what's going on.

If I had to guess, I'd suspect a data toggle error.

Can't you make your device CCID compliant? That's a much better solution for you, Apple, and your customers.

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.
