I am still having the issue but the pain-in-the-ass is minimized since I now realize that you can still sort of "side-load" your .ipa file to your device via iTunes 12.3.0.whatever -I recently upgraded my video card to an AMD FirePro so I'm no longer buying into the installing iTunes for older video cards trick as A. its a pretty new and snazzy video card and B. I don't want older versions of iTunes... I'm a fan of the radio there.
So anywho, I have got this down to a science now so i can rapidly test / retest my app on iOS devices using a development provisioning profile and all the hoops you have to jump through to get your .p12 file (not getting into that):
1. delete prior version of your app from the device
2. publish your .ipa file with your dev profile and p.12
3. delete prior version of your app from iTunes App library
4. in iTunes file > add file to library or drag n drop to the same iTunes library
5. drag the same app now in your library to your device(s)
6. check your device(s) app library, if you have new apps set to install automagicly then you should now see the app on the device / otherwise click install, then sync
Sporadically and almost mockingly I still get the original message about the device list but not such a big deal any more. Anyway hope this helps.

installing version 12.1.3 of iTunes failed to solve the problem for me. i needed version 12.1.2 to solve the problem:
1) Un-install Apple Application support 32 bit/64 bit, Apple Mobile Device Support, Apple Software Update, and iTunes
2) Go to C:\Program Files (x86)\Common Files and delete the Apple folder
3) Go to C:\Program Files\Common Files and delete the Apple folder
4) Go to C:\Users\<your user name>\music\iTunes and delete the .itl file
5) Download and install version 12.1.2 of iTunes: Download Apple iTunes 12.1.2 for Windows 64-bit. Make sure you untick the option to let iTunes automatically update. updating kills the Flash Pro to iOS usb communication (at least, until adobe figures out the problem and releases an air sdk that fixes the issue).
6) Restart your computer
7) Attach your phone to your computer via usb and unlock your phone so if the 'Trust This Computer' prompt appears you're ready to tap trust.
8) Open Flash Pro > Debug > Debug Movie > On Device via USB > click Refresh Device List if your iOS device is not already listed.
9) If that fails, open file explorer and make sure your iOS device appears in file explorer. If it does not, your usb-win connection has a problem. re-check your connections, the usb cable and make you have enabled 'Trust This Computer'.
