Just recently had this same problem with a Mouse G203, (I have a Macbook Air btw), and this is what I did to fix it, when you first launch the GHub software, it ask you to grant permission to access to your system accessibility in order to record your screen if needed, at first I denied it and jump straight to the software and I had the "wake up your device issue", so I went so System Preferences and gave the access it was asking at the beginning and then reboot the software and that was it, it worked immediately and my mouse was recognized by the software. Hope this will be helpful for other Mac users, I dunno if it will work the same for PC users. Luck!!
