Re: "UCM-UCSI ACPI Device" driver keeps appearing and disappearing from the Device Manager

2019-07-09, 9:26 AM

I have the same issue with the following configurations:

 

Thinkpad P1

Windows 10 1903

Thinkpad Thunderbolt 3 Workstation Dock

 

The device "UCM-UCSI ACPI Device" keep appearing & disappering every few seconds, which (maybe) also cause File Explorer changes its focus when I'm trying to rename some files.

 

Lenovo guys, please help to solve this problem ASAP!

You can solve this problem immediately by rolling back to 1809.  We submitted bug about this problem to Microsoft, but so far, they don't know how to fix it (or even debug it).

This is the easiest bug to replicate ever: just connect a TB3 device to a X1E/P1 running Windows 10 build 1903 and you'll trigger the problem 100% of the times.

Based on the above messages, the problem might be caused by incompatible driver & firmware? If so, it might not be only the Microsoft problem but also Lenovo should work out to solve this issue too.

 

From Google search result, I didn't find any other similar problem happened on other laptops!? (If any, please share it!) If X1 Extreme or P1 is the only victim of this problem on Windows 10 1903, it's hard to say that the problem is casued by Win 10 1903...

Do you mean Windows 1903? Also, which Thunderbolt firmware version did you re-flash? The version 1.0.12.0-N2ETG10W from the Lenovo support site?

Yes, just confirmed windows 10 1803, not 1903.

I used this version n2eti04w:

My x1e had the symptoms of this issue along with not being able to turn on with USB 3 lenovo dock button. Reflashing fixed both issues and has worked fine for over 2 weeks now.

 

Read my post on 6/23/19 in this thread for more details.

X1 Extreme / TB 3 WS Dock - Win10 1903 - Device Mgr Constantly Refreshes

2019-07-15, 17:40 PM

After upgrading to Windows 10 1903, I noticed that the device manager is constantly refreshing when docked. I decided on a fresh install and the same behavior exists. Downgraded to Windows 10 1809 and problem goes away. Tried a second docking station and results were the same with 1903. It doesnt cause any issues but very annoying. 

 

Installed the latest docking station firmware and problem still exists. Laptop has latest drivers & FW on all components.

 

When running usbdeview, I noticed that the device name for the Integrated IR Camera changes every few seconds from dotted number to "Integrated IR Camera". As soon as the device name changes, I see device manager refreshing.

 

Model: 20MFCTO1WW

Dock: 40AN

 

Device Manager Video

USBDeview Video

 

Anybody else with the same setup that can confirm this behavior?

 

Thanks

Not sure if it was the new BIOS v1.23 released today, the new TB3 dock firmware v3.1.63 released yesterday or a recent Windows 10 1903 update, but the problem is now fixed on my X1E ?
