3rd USB cord did the trick
I have a new Twiddler 3 and am trying to connect via USB to update the cfg file.
I have tried connecting to two PCs running Win 10 on USB ports that I have confirmed are working. I have tried two different USB cables.
I have tried connecting with the twiddler powered on and connecting first and then powering the twiddler on.
But I have yet to see it appear as a USB drive on either computer.
NOTE: I am able to type with it in Bluetooth mode but when connected via USB
