Hello, thank you for contacting us and sorry to hear about the issue.
1) Make sure you are plugged into a USB port or powered USB hub. We have noticed some errors with some USB-C hubs and are looking into the issue further.
2) Leave the Morph plugged in, hold down the button for 8 seconds, and then press the button again. All the lights on the Morph should flash. If they do not, let us know.
3) When you say "no keystrokes will register", I am guessing you have a Keyboard Overlay. If so, then the Morph should recognize the Overlay when you put it on the Morph. Put the Overlay on the Morph and see if the lights flash.
4) If the Morph is recognized, you should see it on the top left in the menu bar listed as "Morph-XXXX".
Please let us know if this fixes your issues or if there are any other symptoms you can give us to help solve the issue.
