I received an Arduino MKR1500 around a month ago, I managed to connect it to an LTE network and everything was working perfectly. This week, I decided to work on my project again but when I plugged the board in, it was nowhere to be found in my COM ports. Here's what I tried:
I went into the "Device Manager" on Windows, checked the "View hidden devices" option and uninstalled all the previous drivers. I then tried plugging the MKR1500 back in but nothing happened.
I used different USB cables, different USB ports and even different computers, none of which worked. The board seems to no longer be recognizable.
I used the same USB cable and USB port as with the MKR1500, but with my other board, the MKR1000. My PC immediately recognized the MKR1000.
These tests lead me to believe that it's actually a problem with the MKR1500 board, could it be faulty? When I plug it in, the POWER LED and CHRG LED light up (the charge LED is blinking very fast) like usual. Is there something else I can try?
