I've been running Android Studio on my CentOS7 (not Windows) laptop for a while now. I was able to debug my app running on a Verizon Galaxy Note 3. I've now moved up to a Verizon Galaxy Note 4. I enabled Developer Options and I turned on USB Debugging.
However, when I have it look for running devices to run my app, it doesn't show up in the list ("Nothing to show").
What else do I need to do?
