| `dmctl` is the host-side utility for configuring the device at runtime. It can be used to query device info, switch to another mode, or perform a few mode-specific commands. | ||||
| 
 | ||||
| Communicating these commands happens over the USB vendor interface. | ||||
| 
 | ||||
| ### General usage | ||||
| 
 | ||||
| The `dmctl.sh` script can be found in the `host/` directory in the source tree. | ||||

| ### 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>`. | ||||
