Thanks for the update.

We see the same issue on nRF Connect Programmer and investigate it now. Sorry for the inconvenience.

I have installed the firmware on my dongle using nrfutil using the file connectivity_4.1.4_usb_with_s140_6.1.1_dfu_pkg.zip.

It now works.

Can you please explain why installing the firmware using nRF Connect Programmer does not work?

Hi, I have tried every single port of my MacBook Pro (I use a USB dongle connected to some of the thunderbolt port of my Mac), but the problem persists.

I can not do the procedure to disable MSD on my mac because I do not have J-Link OB. I think that can not be a solution because affected devices are DK, and I am using a dongle. That also seems an operation to do on the device, not on the computer (I have done it to develop with my DK).

The usb driver found on System Information panel on my Mac is: AppleUSBVHCIBCE. Hope this can help.

Hi,

What J-Link firmware version are you using?

Can you try disabling J-Link MSD on your computer as well to see if that helps, described how to do so here.

Have you tried other USB sockets on your PC? Typically some may have power, some may have USB3 some may have USB2, etc., and also the internal routing inside the PC can lead to differences.

Could you provide more information about the USB CDC driver on the computers having this issue? The driver info in the Driver Details pane would be helpful.

Hi Amanda,

thank you for helping me, but with the hex file you suggested I obtain the very same error.

Hi,

You can test with the FW which is posted by Jørgen here. The "External LF crystal" version (200505_ble_connectivity_s140_usb_hci_pca10056_lfxo_mergedsoftdevice.hex ) should work for the Dongle.

Regards,
