I got a SparkX Qwiic USB Development dongle and it was working fine. But then it stopped completely. It shows up in Device Manager as a correct COM port. Arduino IDE sees it but will not write to it (it says there is no device).
If I try to connect via TeraTerm, TeraTerm just locks up.
I’ve had it 3 months and it’s now out of warranty. Is there some way to fix this? Anyone else have this problem?
Thanks!
