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.

  • I had a similar sounding problem with the MKR1300. It occurred after I tried to use the sleep library.  I found that if I held the reset button down while flashing, and then released it just before the PC attempted the upload I could get it to load.  The trick was to start the flash before the MKR1300 went to sleep and timing on release of reset had to be in a window or it would not work.

    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.

    Thanks Frank fmilburn.

     

    The OS is not able to enumerate the serial port for the MKR WiFi 1010 so I have no way of loading the board with any sketch on to the board.  I've seen something similar to what you see with the MKR1300 with an ESP8266 in the past but in that case the OS could enumerate the serial port.

    Probably not the same....  I think the MKR1300 would enumerate and then since the sleep mode call came very quickly after powering up it would drop out.  At first I thought it wasn't enumerating at all since the message was that the USB device was not recognized IIRC - kind of an ugly bug.

    Ah, yes close.  So I went back to find some old postings on the Arduino community forum, where I posted this issue as well, and found a post I made some time back for the MKR1000.  There was a recommendation to double press the Reset switch on the MKR1000 when it was plugged in but that did not seem to fix the issue with the MKR1000, but when I did this with the MKR WiFi 1010 the USB connection enumerated and the device appeared again in the Arduino IDE from which I was able to load the basic blink sketch.  I'm not sure what happened to the board to get it in that bad state but it seems to be working now. Strange.

     

    This is what I see in Ubuntu now:

    I'm happy again.

  • So I had the similar problem. I had two MKR WIFI1010 boards, both stopped being recognized on my Windows 10 PC. Then I tried on the Mac and on my Raspeberry Pi , and none was recognized. I kind of gave up on them thinking it was an issue with the board drivers. 
    Today I came back to them, I examined the micro USB connector on the board under a magnifying glass, and voila... it was the connector plate pushed way back to the casing. Used a small flat-edge  screwdriver, pushed the plate back to ensure good contact with the cable and YES. Both boards are back in business.
