Dell DA200 Adapter ProblemT (Code 31)-A USB port reset request failed.

Suddenly my Dell DA200 Adapter doesn't work on my Dell XPS 13 9360.    HDMI & VGA can still work projecting to my monitor, but USB and LAN stops.

Tried uninstall, reinstall, update USB drivers to no avail.  Last resort was to clean install but problem is still there!  It's only been 3 months and I practically did nothing different than yesterday (no new install, change/update driver, etc.), just stopped today!

Tried the hdmi adapter to the USB-C and work, also showing it as billboard device, whilst the DA200 don't show.

Want to tried to wifi power setting, but couldn't find it in the device manage->network adapter?

Any idea what should i do?  Faulty adapter seems to be the last answer, but it's practically new and it was working flawlessly before.  Will i be able to claim warranty on it?

Thanks
