I'm running FreeBSD 12.1-RELEASE-p4, and when the system boots with a Yubikey present (or I believe the first time I insert it), the key will work appropriately as a U2F token, or a keyboard input as needed. However, after I detach it (sometimes it's the second or third time I detach it), the USB system seems to just hang. The USB mouse continues to work fortunately, but any new USB device I attach isn't recognized (no dmesg messages at all). I'm not even sure where to start; I've googled as much as I can and have found very little with which to troubleshoot. "usbconfig" or "usbconfig list" just hangs; ctrl-c will break out of it, but otherwise it'll just hang with no return on the terminal. My latest dmesg shows the yubikey connecting, and then disconnecting when I legitimately pull it out), and then when I put it back in, nothing. ugen0.8: <Yubico YubiKey OTP+FIDO+CCID> at usbus0 ukbd0 on uhub2 ukbd0: <Yubico YubiKey OTP+FIDO+CCID, class 0/0, rev 2.00/5.24, addr 8> on usbus0 kbd2 at ukbd0 uhid0 on uhub2 uhid0: <Yubico YubiKey OTP+FIDO+CCID, class 0/0, rev 2.00/5.24, addr 8> on usbus0 ugen0.8: <Yubico YubiKey OTP+FIDO+CCID> at usbus0 (disconnected) ukbd0: at uhub2, port 4, addr 8 (disconnected) ukbd0: detached uhid0: at uhub2, port 4, addr 8 (disconnected) I run usbdump, and the only traffic I see is going to the mouse and the USB hub where nothing but my mouse is (that's continuing to function).
