P52: IR Camera Failed

2020-08-24, 10:42 AM

The IR Camera performs random failure with the latest driver on my ThinkPad P52 with Windows 10 Pro for Workstation since 2019. 

In the Device Manager, the IR camera may disappear from the list and become an Unknown USB Device (Device Descriptor Request Failed) term. 

I tried to upgrade the driver from Lenovo Vantage and Windows Update, and replace a new camera module from Lenovo Service, but the problem still exists.

 

Sometimes after a fresh reboot the IR Camera may work properly, but it may fail more often. This issue break down the Windows Hello faces sign, which causes much inconvenience.
