instead of giving the text you want to type as a parameter, you now have to pipe it to `scan`. this means, you can directly pipe the output of `pass`

PASSWORD_STORE_GPG_OPTS="--passphrase 12345" pass show github.com/girst | sudo ./scan /dev/hidg0 2 2

will type my github password for example. (using the latest `pass` version from their git).
