nrfutil device command doesn't find FTDI dual RS232 USB adapter starting from version 2.8.6

[Jonas Keller]

I have an FTDI USB to dual RS232 adapter for communication over UART. The nrfutil device command finds it in version 2.8.5 and below:

C:\Users\jkeller>nrfutil install device=2.8.5 --force
nrfutil-device already installed
Uninstalled nrfutil-device

Product         Dual RS232
Ports           COM49, vcom: 0
                COM48, vcom: 1
Traits          serialPorts, usb

FT3KVHRP

Ports           COM58

Starting with version 2.8.6 it doesn't find it anymore, but it still finds the other USB to RS232 adapter I have connected to my pc:

C:\Users\jkeller>nrfutil install device=2.8.6 --force
nrfutil-device already installed
Uninstalled nrfutil-device

Ports           COM58
Traits          usb, serialPorts

Supported devices found: 1

The problem still persists in the current version 2.15.1 of the device command.

I have noticed this because the Direct Test Mode App doesn't show the dual RS232 adapter anymore, starting from version 2.5.0, where the nrfutil device command it uses was updated from version 2.6.4 to 2.10.2.

Hello,

Thanks for letting us know. It seems hardware is ok as it works on previous version. I can't see any information related to this on the change log of version 2.8.6.

I have asked our team. I will get back to you soon.

Thanks.
