Hello @Jacques-Zhao thank you very much for your contribution! I have 2 general topics to discuss:

1. I can see that there are few TODOs in the code. Could you please share your plans or design documents about what should be implemented before this PR is merged?
2. Are there any fields in the NCM descriptor that the user might want to change? (usb_descriptors.c, line 190)
