The device I am trying to forward is Yubikey 5 (Its has worked rather reliably in the past).
I can see the device and can start the forwarding steps but it fails at the final step where there red circle with an exclamation mark instead of a green circle for success. No I do not use any other usb sharing software.
(Maybe relevant) I have gnupg2 installed using MacPorts, it comes bundled with wget. I don’t activate gpg-agent or always kill gpg-agent before forwarding Yubikey but it is not reliable in terms of forwarding success.
I only have one MacBook.
