KB4586853 Fixes Thunderbolt NVMe SSD Stop Error

A couple of months back, Windows 10 starting crashing when I would plug a USB-C NVMe device into one of my Belkin Thunderbolt docks. I soon learned this was a known gotcha, and simply switched to plugging the device into my USB-C/Thunderbolt port instead (which kept working). As per the Windows 10 20H2 Known and Resolved Issues page, KB4586853 fixes Thunderbolt NVMe SSD stop error.

As you can see from the following Device Manager screen cap, all of them list a Conexant SmartAudio HD device as the first entry under Sound, video and game controllers. Given the gotchas out there, I’m happy when they don’t bite me!

Although my newer (2018 and later) Lenovo laptops all include Conexant audio chips, none seems affected by the unresolved issue for such devices. Dodged a bullet?

In general when things get weird with devices or their drivers on Windows 10, I usually check the issues list before I go into heavy-duty troubleshooting mode. As with the Thunderbolt NVMe device issue just resolved, such issues do bite some of my PCs some of the time. Thus, this saves me from trying to solve problems that other, better-equipped engineering teams are already working on. Now, if I could just learn to be patient while those fixes are in progress…
