I've bought a pair of yubico devices to play with for various projects, however, it's struck me that they are not working on debian 10. I understand there's a few bug reports and udev rules floating around to mitigate this, but after having tried several of these suggestions, I am still not having success.

Here's what I know:

  • USB device is recognised by the kernel and listed under lsusb

Bus 001 Device 097: ID 1050:0120 Yubico.com Yubikey Touch U2F Security Key

  • I have yubikey-personalization version 1.19.3-3+deb10u1 installed but it's not able to communicate with the device
$ ykinfo -a
Yubikey core error: no yubikey present
  • I am running the following udev rule under /etc/udev/rules.d
SUBSYSTEM=="usb", \
  ATTRS{idVendor}=="1050", ATTRS{idProduct}=="0010|0110|0111|0114|0116|0120|0401|0403|0405|0407|0410", TAG+="uaccess", GROUP="plugdev", MODE="0660", ENV{ID_SECURITY_TOKEN}="1"
  • I believe the udev rules are being applied by observing udevadm (:uaccess: tag won't appear without this rule)

  • The thing still won't work. I've straced ykinfo -a and I can see it querying the device under /sys/devices/* but I can't tell what whould have been happening. (I haven't had the chance to consult the code yet).

Does anyone know or understand why it is not working, what can I do to further debug the issue, what I may try to fix it? If anyone has a working yubico security key on debian 10, please could you share information so I can compare notes please?

The security key only has FIDO / U2F support so ykpersonalize/ykinfo does not work with it.

Use Yubikey manager: https://www.yubico.com/products/services-software/download/yubikey-manager/

  • Thanks @Gabriel. Is that as opposed to offering OTP? – Pedro May 19 '20 at 14:32
  • Got it. Hardware is fine, I can use `pamu2fcfg` with it. Looked through the documentation of yubikey-personalize and there's no references to it handling OTP (and possibly challenge-response) only. – Pedro May 19 '20 at 14:45
