### Connecting to a device
While it is possible to have `dmctl` connect directly to a USB device (using `--conn vid:pid` or `--conn bus.dev`), having the kernel module loaded will keep the USB vendor interface reserved for itself. To work around this problem, a character device driver has been made, which exposes a `/dev/dmj-<id>` device which can also be used by `dmctl` using `--conn /dev/dmj-<id>`.
