Had the same problem and just plugged it into a different port.
Nope. I’ve tried that already as well as several different computers.
If I restart the computer with it connected, it normally finds it.
Unfortunately that doesn’t work either.
Stupid question this but… Have you use the right USB for it?
No sure it’s the right one. In fact I have two USB cables for it and neither work.
Any corrosion in the port? I had this issue and eventually had to pay for a reconditioned unit.
Not that I can see but the Google search revealed that that is the most likely reason. I did have a very wet ride a few weeks ago but have uploaded since then without any issues. When you say reconditioned unit do you mean the port or the whole device? How much did it cost if you don’tmnd saying?
