Metro Mini 328 Com Port not Showing

by CornChippy on Wed Feb 06, 2019 6:23 am

Hi all,

I recently purchased a metro mini 328 and am having trouble getting arduino code to upload to it.
The main issue is that there is no new com port showing in the device manager window when the metro is connected to my pc (even when show hidden items is checked).
I've read through another forum topic (viewtopic.php?f=22&t=78579) where the same issue occurred.
I believe my metro might have the same usb-to-serial converter issue discussed there.

Is there a way to fix this from home or will a replacement need to be sent?

Thanks for the help,
CornChippy

First, as a sanity check, verify your USB cable by using it to connect some other, known-working device to the computer.

There's a plague of charge-only cables out there with USB connectors at both ends but no wires for the data signals. We see people get caught by them every day.

Just swapping to another cable doesn't prove anything.. it's become normal for people to say they had to try three or four cables before finding one that worked. You need to true positive of a working connection to rule out the false negative of a charge-only cable.

Hi Mike,

Thanks I didn't even think to check that.
I used a different cable and now the metro is seen by my pc.
Thanks again for the help.

Regards,
