Hello, everyone. I want to implement a compound device. It has two protocol: CCID and FIDO HID.I have some problem with it. How to select protocol? FIDO HID can interrupt CCID to process its commands if CCID is working?

A device can supports many interfaces. Your CCID and HID is a hardware. And they should have different end points. You can identify which protocol received by end point.

Would you give a piece of code OR more details about USB compound device as a reference?
Thanks.

It is so easy. You only need two interface descripters and a config descripter. One of the interface descripters is HID descripter. The other is CCID descripter.
