X1 Carbon 5th Gen: USB C devices not detected after Windows 10 upgrade to 1709

2017-12-19, 2:10 AM

Help!

 

I have a Lenovo Thinkpad X1 Carbon 5th Gen (model 20HRC) that's about three months old. I've successfully used it with an Anker USB 3.0 hub that offers an Ethernet port and three USB 2.0 ports.

 

After upgrading to Windows 10 build 1709 in October, the Anker Ethernet connection is no longer detected when I insert the USB C connctor. Neither port works. If I put a USB memory key into the Anker hub, it is not recognized, either. The same USB memory key is recognized if I insert it into the USB 2.0 connector on the right hand side of the laptop.

 

When I connect my phone to the USB C connector, it is not recognized, either.

 

The Anker USB Hub and my phone are both recognized when I connect them to my other laptop, so I have no reason to believe they're defective.

 

Before I call Lenovo for support, what else can I check?
