Is USB CDC ACM supported on NRF52833?

[seneryilmaz]

I've recently flashed USB CDC ACM example to NRF52833. Even though everything seems to be working, there is no COM port listed on Windows. I've also tried Zephyr's USB CDC ACM, again it seems to be working but nothing listed as COM port. When I try same examples with NRF52840, they work pretty well.

I saw the text below in a website.

Is this might be the case?

What version of the nRF52833 DK are you using?

I am using a custom board based on the NRF52833. I've purchased 2 NRF52833 DK boards as well but they're not arrived yet.

I've found another board that has a NRF52833 Rev. 1. It's working properly with this board. I think the previous board has engineering sample A revision.

That sounds like the most likely issue. I'm glad you've found a solution though!
