Troubles with Unity Remote 5 and Phone Detection

Hi everyone!!

So, to make a long story short, I installed both android SDK and JDK, found the best drivers for my phone (a Vodafone Smart Prime 6, which is just a rebranding of the Alcatel Pop 2 (5)) which is now detected in the windows device manager. Eventhough all of the above is true, when I run the command prompt and execute the command "adb devices" in "\android-sdk\platform-tools" the device list is empty; so, my understanding would be that, although the phone is detected at a superficial level (the windows device manager + I can explore the phone's folders), the computer isn't fully connected to it as, and this is the final and fundamental point, running Unity Remote 5 and going through all the required steps to have the game work on my phone won't work.

As a side note, just to help you cross it off of the list: yes, I went through all of the Unity Remote steps correctly, I think: plugged phone in, activated USB debugging and mock locations, started app and then Unity on my pc, went in Edit->Project Settings and selected "Any Android Device", hit play (duh!).
