Seeeduino XIAO COM Port Problems

I’m very impressed with this board so far. I was also having the same issue, getting frustrated, thinking, WHY WON’T THIS UPLOAD!!! Then saw the post below and tried the same cable that comes with Google Coral TPU USB stick, and IT WORKED!!!

Not all USB C cables are the same it turns out. There’s probably a way to check the cable using a USB C female connector on the other end that breaks out the pins. Something like this should work in testing the cables: Adafruit USB Type C Breakout Board - Downstream Connection : ID 4090 : $2.95 : Adafruit Industries, Unique & fun DIY electronics and kits

If that doesn’t work and the reset doesn’t work then I don’t know the answer.

I know Im late to this party but I was having trouble connecting to my XIAO and I found out what the problem is in my case.

I had bought some JBL headphones that came with a USB C cable so you could charge them. It is orange and flat, I tried to connect to the XIAO with that assuming it was like any other USB C cable.

Turns out some cables are ONLY for charging, this one has no markings to indicate that. I swapped to a round USB C cable and the COM port comes up straight away and everything is working as expected now.

Yes this happened to me the other day… i was cleaning up and threw a USB cable into my box of stuff and it was also a Power Only USB cable… I am going to try to find some red fingernail polish and put on the end of the cable to help not to make that same mistake again

After trying for a while to get the Arduino IDE to recognize my Xiao, I finally remembered having read that power-only USB-C cables can be the cause of this. And, sure enough, a different USB-C cable did the trick! Like you said, @cgwaltney, some red fingernail polish is in order!!!
