nRFConnect 3.0.0 unsupported device "serialport"

[Dave_couling]

I updated to nRF Connect 3.0 today and its seemed to causes issues with any Dongles I connect to my PC.  I get the following error:

ERROR Unsupported device with serial number 'CD28EC9EE85A' and traits ["serialport"]

I tried uninstalling and reverting to 2.7 but the issue seems to persist.  I've tested on 3 dongles and I get the same error everytime.

Hi Dave, 

I'm sorry for the delayed response. We are on reduced staff during the summer. 

When I tested on my computer, on the first run after programming the board I saw the exact same error code but then nRF Connect showed an error regarding LibUSB and asking for reset of the software. After that the dongle worked as expected. 

Could you try to put the dongle into bootloader mode (press the reset button on the dongle, red LED should breath) and program the chip using nRFConnect ? 

Could you update the Jlink driver to latest version ? 

If the issue remains, I would suggest to use a NRF52 DK instead of the Dongle. You will have more control for programming the chip compare to the Dongle.

Hi Hung,

I had tried this, but programming seem to fail.  When the device would reset, my computer would be assigning it a COM port number.  Somehow this process causes issues with the FW updates.  I plugged my dongles into another computer which successfully programmed them.  They work fine back on my machine, but I am concerned of this occuring in the future.  Atleast I know a fix, but want to post this in cases other experienced the same issue when upgrading to nRF Connect V3.0.0

I've recently updated to Connect 3.1.0 however I still see the same error.  I was able to replicate this error on two other co-workers machines

Hi,

We have seen some similar issues previously, and it seems to be related to the USB port or hub used. When reproducing, did you do so for the same type of computer and using the same USB port? Can you check multiple ports, and directly to the computer instead of through hub or docking station, to see if any of that helps?

Does the nRF52840 Dongle list in the pulldown menu of the BLE app, like this?

Can you provide a full list of steps for reproducing?

This is still a problem with the latest nRF Connect v3.2.0.

Shows similar except without the "USB: Nordic Semiconductpr nRF52 Connectivity"

This suggests to me that the firmware in the dongle isn't working properly.  I let the nRF Connect attempt to update the firmware once in bootloader mode, but the FW updates always fail.

Here is the log:

I have tested on all available USB port with the same result.

Hi,

Thanks for the update.

You mentioned earlier that a workaround was to program the dongle on a different computer. Was that a computer with an earlier version of nRF Connect for Desktop, or was there another difference between the two?

Yes that other computer had a much earlier version
