Exact error:
Severity Code Description Project File Line Suppression State Error DEP0001 : Unexpected Error: -1988945906 TestApp

Version of OS: 1511, Windows 10 for phones 10.0.10586.164
I got a similar error.
The reason the error occurred for me was because I forgot to add the new splash images in assets after deleting the old ones.
The solution was to add the images. To get the correct image names and sizes, I used this extension for visual studio.
So, I think I get the trick. After plugged in your Windows Mobile device, Windows App Deploy can see W10M device, but once your device goes to lock screen, WPD can not detect it anymore.
You should to plug out and plugin again, with screen unlocked, to make it detectable. (I'm not a really English speaker).
I had the same issue, and found that in my case it was occurring while the phone was downloading system updates in the background. App updates/installations from the app Store were also prevented from downloading/installing.
After the update had finished, all was back to working again.
As Windows Phone 10 doesn't seem to make it obvious that it's downloading updates, maybe worth checking this out if you hit this problem.
I've experienced the same problem after updating Visual Studio community to Update 2. Typing in CMD (under admin rights) the following command solved my issue:
Thanks to Agrgg for a good tip ;)
I had the same error with deploying onto Windows Phone 8.1 device. In my case the problem was in Windows Phone IP over USB Transport (IpOverUsbSvc) service, which wasn't running. The deployment error disappeared after I'd started the service manually.
For me, it was as simple as unlocking the phone so that the computer would have access to it.
