One of our customers reported a strange error with CP2101 driver on Windows 10 :
When trying to install the drivers, an error message indicates that the device cannot run on USB 3.0 port.
Here is a screen caps (sorry, it's in french). Translation would be something like this :
"Silicon Labs CP210x USB to UART Bridge is an anterior USB peripheral which cannot run with USB 3.0. Connect the peripheral to an available USB 2.0 port, then click on Next. Else, click on Cancel."
I cannot check this issue as I do not have a computer running Windows 10, with USB 3.0 ports.
Any idea or workaround concerning this issue ?
Thanks for your help !
I have not been able to reproduce this issue using a CP210x device, the CP210x Windows 10 Universal Driver, and Windows 10 environment with a USB 3.0 port. Can you please try the following and/or provide the following information:
1) Try uninstalling all versions of the driver completely and reinstalling.
2) Please provide detailed step-by-step instructions to reproduce the problem. Specify when the actual CP210x device is connected, if at all, in relation to driver installation steps.
3) Has the CP210x device on the board/product been customized in any way? If so, how?
Thank you, and please let me know if you have any questions.

Method 2: Disable USB 3.0/3.1 eXtensible Host Controller
“USB device not recognized. The last USB device you connected to this computer malfunctioned, and Windows does not recognize it.” or “Eject USB Root Hub (USB 3.0)” often appears on computers with the Gigabyte Z170X motherboard, so if you seldom use the USB 3.0/USB 3.1 port on the back of the computer host, you can disable the USB 3.0 eXtensible Host Controller in Device Manager and fix the USB 3.0/3.1 not working or not recognized problem on Windows 10 Creators Update or Windows 10 Fall Creators Update computer.
1. Go to the Device Manager.
2. Expand the Universal Serial Bus controllers.
3. Right click the USB 3.0 eXtensible Host Controller.

Hope these methods solve your problem.
