Artemii Bigdan suggested a patch for Nitorokey 3.
I found:
https://github.com/Nitrokey/nitrokey-3-firmware/blob/main/docs/index.md
So, we can support it better.

Following the description of https://github.com/Nitrokey/nitrokey-3-firmware/blob/main/docs/usbip.md
I managed to run it by cargo run --features ccid.
I can see it by lsusb:
... ID 20a0:42b2 Clay Logic Nitrokey 3A Mini/3A NFC/3C NFC
But it fails (disappeared) when I do lsusb -v -d.
When I do usbip attach -r localhost -b 1-1 again, it appears again.
Unfortunately, it does not work out-of-box. I'm using in-stock CCID driver of GnuPG.
$ gpg --card-status gpg: OpenPGP card not available: Invalid value
Let me debug it.

I need this patch for ccid-driver.c (which is not clean, but device specific):
