No problem - I’m glad it worked. No, you’re in good company as it’s a new device/concept for many. Most have travelled the road before you, and between the configuration and set-up information on the DigiRig site, and searching this forum, often the answer is there. It can be a, “I can’t see the trees for the forest,” situation though. 
When you say it just shows up as a USB Device, is that within the app/software you’re trying to use, or Windows Device Manager? In both of those cases that is normal, but you can rename it to whatever you wish for better clarity.
To rename it:
-
Right click the speaker icon in the bottom right of your screen, and select Sound Settings;
-
In the pop-up System > Sound, scroll down to More Sound Settings;
-
Select More Sound Settings;
-
In the pop-up Sound, Playback, double click the 2- USB Audio Device (named Speakers if I recall);
-
In the pop-up under the General Tab you can change the name to whatever you wish. I used, DigiRig TX-Speakers, to ID it as the DigiRig device and to clarify for future that speaker audio levels are the radio transmit levels (audio into the radio);
-
Select Apply; and then select Okay;
-
In the same pop-up from step 4, select Recording; and
-
Repeat step 5 and 6, but this time I used DigiRig RX-Mic to clarify for future that the microphone audio levels are the receive levels from the radio into the software.
Optionally you can also change the icon at the same time as you change the name as both are in the same location. I went with a modem icon, as suggested by the designer of DigiRig @K0TX vs. the default speaker and mic. It makes it much easier to find the DigiRig when in the mixer or apps.
Now whenever you’re looking at a device selection in Device Manager, an app, Windows mixer etc., the DigiRig and the related audio level will standout from the other selections.
Within the apps you will have to select the DigiRig Tx and Rx audio devices, set their audio levels using the app and/or Windows mixer, and for PTT/serial you’ll need the COM port number assigned to the DigiRig, which you can find in Device Manager under Ports (COM & LPT).
If it comes up in a setting option, DigiRig Mobile uses the left audio channel for the speaker/mic audio, and the other gotcha is that Windows will make any new audio device the default; your new DigiRig in this case.
You will have to make another audio device your default (speakers, screen speakers, microphone etc.) otherwise any audio like system beeps, YouTube audio, sounds in the room will be routed to the DigiRig - not a good look having that audio going out over the radio. Lots of info on that if you’re not sure how to, and it’s done from the Windows mixer.
Oh, and that bruising on one’s forehead from banging it against a wall, will subside in about 10 days. 
Now you can go have some fun with the new toy.
