Packages are not allowed to write to /var, so to run pcscd on Guix you
will have to symlink ~/.guix-profile/pcsc/drivers to
/var/lib/pcsc/drivers manually, until we have a system service for
pcscd. Can you try that?

This would work, but ccid is one of potentially many drivers for pcscd,
so I'm reluctant to "hard code" it. It would not be possible to use
other drivers if usbdropdir is set to the ccid output.

Thanks for checking!
