I have tried this fork and the original and I just can’t get fw-ectool to work. I am running Debian bookworm and installed `libusb-1.0-0-dev` and `libftdi-dev` to fulfill build dependencies. Then I built the package with `make utils`. Both in the original and the fork, I get this error:

```auto
sudo build/bds/util/ectool --interface=fwk version
Cannot open lockfile /run/lock/cros_ec_lockCould not acquire GEC lock

```

(Obviously, in the original, `--interface=fwk` doesn’t work, so I didn’t pass that.)

What am I doing wrong?
