MKR WiFi 1010 - USB device not recognized

jomoenginer

So, I think I may have a dead MKR WiFi 1010.  It was working for a bit but now it is not recognized by 2 separate computers with either Ubuntu or Windows 10.  I've been testing with the MKR Relay Board and trying to create a project for the Arduino MKR contest but the MKR WiFi 1010 is no longer seen by my computers or the Arduino IDE so I can not upload sketches to it any more.  Powering on the board with the Reset button pressed has not reset the board so I was curious if there was another way to clear any nasties in the board to get it working again.

 

The same cable connection works fine with a MKR1000 but not with the 1010.

 

Anyone else run into this?

 

Cheers,

 

Jon

  • I doubt this is your problem but my MKR WAN re-enumerates the USB port whenever it switches from application to program mode, so the arduino IDE serial port has to be reset 2 to 3 times during a program cycle.

    Yeah, I've seen this where the COM instance changes when unplugging the board on a Windows system or it toggles between ttyACM0 and ttyACM1 on a Ubuntu system which is normal.  However, in this case, the system sees that a USB device is connected but it can not get any info from it to recognize what it is so the serial port instance will not enumerate thus no COM or ttyACM# port is created.  

     

    On Ubuntu I see this error that gives me a feeling that something went back on the board.

    [38157.748110] usb 2-7.2: new full-speed USB device number 29 using ehci-pci
