Unknown USB Device on a ThinkPad A475

Hi,

 

I have a new ThinkPad A475, just formatted it with the latest Windows 10 1709 build. I have installed all the drivers with the Lenovo Vantage app but there is still one "Unknown USB Device (Device Descriptor Request Failed)" in the device manager. Searching for an updated driver in Windows Update doesn't work and I also downloaded the SCCM driver pack for this model but no INF file seems to work.

 

Here is the ID of the device in question:

 

USB\VID_0000&PID_0002\6&37593720&0&3

 

Thanks!

 

JF

I sent my laptop for repair and it turns out the motherboard was defective (the webcam was not working), they replaced the board and now it works.
