Hello, new user, working with a VOXL2 Dev kit. 

A coworker was working on our VOXL 2 and we had success in uploading our AI and getting it all working. We were able to connect through ADB and also through ssh. We updated the device and have been testing different aspects while preparing our drone frame. 

We are now currently unable to view the device through the adb devices list. 
I noticed in our voxl-inspect-services that we are missing the docker-daemon as a service.

I am by no means an expert, like stated above, very new user, more of a drone expert than a software expert. 
Is Docker-daemon something we can reinstall? 
Our team has made many changes to the VOXL already and do not want to erase all our work so far. 

Any help would be greatly appreciated.

Can you please clarify this statement? if you are not able to view the device in adb devices list, this means you are not able to connect to the device via adb, but you are showing the output of `voxl-inspect-services` - how are you running that? Are you using an SSH connection to the board?

@Alex-Kushleyev 

Thank you for your response @Alex-Kushleyev. 

Yes, we were able to set up the WiFi and can ssh into the VOXL2. 

I am quite new to the developmental side and per my understanding we have been able to access and change what we would like through the ssh, but I was curious if this lack of docker-daemon has any negative effects AND if this is the reason we can no longer view the VOXL when using the USB-C to USB-A cable. 

We did have ADB working when we first received the platform as we were able to log in and modify the WiFi settings among others. We are not sure what changed but now we are no longer able to connect to the VOXL via the USB yet we had success with previously.

@Stefan-Amundarain 

on some systems, you need to run adb in root / sudo mode in order to access VOXL2.

Can you please try the following on your Linux host machine:
```
adb kill-server
sudo adb shell
* daemon not running; starting now at tcp:5037
* daemon started successfully
```
hopefully this works. after first time (with `sudo`), you don't need `sudo` in the `adb shell` command until you reboot your host machine.
