[Message part 4 (text/plain, inline)]

I've been unable to use my gnuk usb smartcard token with gnupg on
GuixSD, and it appears this is because scdaemon is built without libusb
support:

      $ gpg --card-status
      gpg: selecting openpgp failed: No such device
      gpg: OpenPGP card not available: No such device

Attached is a patch that gets scdaemon working for me and a gnuk...

Unfortunately, enabling libusb causes one of the tets to hang
indefinitely:

      PASS: tests/openpgp/decrypt-session-key.scm
      Checking unwrapping the encryption.
          > encsig-2-keys-3 encsig-2-keys-4 <
      PASS: tests/openpgp/decrypt-unwrap-verify.scm
      Checking signing with the default hash algorithm
          >

So far, I've only been able to get it to work by disabling the
tests... so it's obviously not a good idea to enable without further
troubleshooting.

Another option might be to use pcsc-lite and ccid, but I had even less
luck getting that to work.


live well,
