Subject: Re: [Zephyr-devel] How to run samples/subsys/usb/console on windows with nrf52840_pac10056?
After updating my zephyr code to latest, I found some patch already done both on USB driver and sample. Good job!
And the result of console sample on my win10 PC is changed, there is one more Zephyr port, looks the USB device already be recognized, but still not works.
Any patch pending not merged?

Do they use MS OS Descriptors to pick right driver? We have this
capability in Zephyr, it is used in RNDIS to pick RNDIS compatible
You can also create issue for the sample.
