Identify if J-Link driver is required for nrf52840_DK

[Aleksei]

Hi support,

Some versions of nrf52840_DK come with J-Link which requires special J-Link driver on Windows, e.g. PCA10056 2.0.1 2020.7. This driver is not installed automatically with "J-Link Software and Documentation Pack" anymore. From here:
> The option to install the USB driver is not part of the installer GUI anymore. This is because all SEGGER probes in maintenance period are using WinUSB drivers per default. The USB driver is only required for probes which are out of support & maintenance period.

How a user can identify if nrf52840_DK requires J-Link driver installation?

Hi, 

Please install the nRF Command Line tool which includes the required firmware.

Hi Amanda,

Thank you for the response. I understand that nRF Command Line tool may install necessary driver, but we would like to avoid having it as mandatory step for our users.

Our context: we are making shield which connects to nrf52840_DK. We have Python application which gets data via UART from nRF52840-DK and we are trying to make a good user experience by simplifying setup process.
"New" nRF52840-DK works fine on clean Win10, while "old" require driver installation. Most likely users will have "new" boars, but case with "old" boards has to be documented as well.

nRF52840DK has updated the interface MCU since HW v.3.0.0, but I am unsure if this is the reason for that.  

e.g. PCA10056 2.0.1 2020.7.

This is HW v2.0.1.
