Good day and welcome to the community.
It would be useful for other members if you'd provide more information (steps you've tried, prior state of the machine, any error messages, etc), otherwise it will be difficult for the community to assist you.

One of the problems with running Insider Previews is that manufacturers may have not yet created updated drivers for the devices used in your system. If the problem only exists within the insider preview build(s), your should post the problems you are seeing in the Insider program's feeback hub so they can get that resolved before the public release.

I agree with JDGillis. Please report this via the feedback hub or at least post on Microsoft's forums so Microsoft can address this ASAP. The Fall Creators Update is only a couple of days away. We don't want other Yoga 900's to have the same problem.
Thank you for your cooperation.
I am not employed by Lenovo or Microsoft. I am a volunteer.

I have reported it to Microsoft feedback but I still would like an updated driver. I have run these updates for years and this is the first time I have had a problem. This has been a problem reported off and on since early 2016, I first thought it was a failure of my laptop. I am using the slower ring not the more experimental ring Lenovo should have updated drivers because The Creators update was scheduled to be released in late September. Microsoft does not have a procedure to roll back all the way to the stable track. Removing myself will only leave me stuck without workable USB.
