Serial Port Issues

by waltdisgrace on Mon Jan 14, 2019 2:57 pm

Hello,

We ordered several Adafruit Feather 32u4 RFM95 LoRa Radio devices. Within a few months, two of them stopped being able to connect to a computer via USB — as in, after we plug a USB cable into the device and the computer, no change in the list of available serial ports occurs. We are using working, data-transmission USB cables.

Are there any ideas as to why these failures have occurred? Were there problems with these devices when they arrived or is there something we can do to avoid this with our other devices? Is this a common problem with these devices?

Invoice number is 1889914.

Thanks.

Does the red LED near the Feather's USB jack pulse when you double-click the reset button?
