Hi Jansen98!


Welcome to community forums


What version of Windows are you running? According to the list of compatible devices to run Windows 10, the machine is compatible up to Windows 10 1803 and you can refer to this link: https://support.lenovo.com/do/en/solutions/ht506455.

 

You can try uninstalling it from the device manager and restart the computer. Run the update from the Lenovo Vantage app and install all detected updates.

Let us know how it goes.

I am having this issue.

Received our Pro last week. Plugged it in; worked fine. It seems we got a Windows update last week (1803) and now we get USB errors when we plug it in.  In the device manager, it shows up as "Unknown USB Device (Device Descriptor Request Failed)". I've heard there have been some issues with 1803. Wondering what I should do with this paperweight. Thanks!

 

Here are my specs:

Alienware AREA51R2

Intel i7-5820K

GeForce GTX 1070

Windows 10 Pro 1803

@ellamacrow
You might want to consult the support team of the manufacturer of your machine regarding this.
