UCM-UCSI ACPI Device driver error

Hello, I have some problems with my HP 846 G9 laptop with Windows 11 22h2. My USB-TYPE C ports have problems.

For the UCM-UCSI ACPI Device, it reports an error that "Windows has stopped this device because it has reported problems. (Code 43)".



UCSI PPM failed to complete the UCSI command promptly. Please contact the UCSI device or system manufacturer to investigate.

(Command: SetNotificationEnable)

When I try to plug in a USB HUB with an HDMI port and try to use an external monitor connected to the HUB, no connection is reported and no image appears probably due to the UCM-UCSI ACPI Device driver error.

 

UCM-UCSI ACPI Device driver error

Hi Gaetano,

I've had the same problem with UCM-UCSI ACPI Device driver 43 error on Windows 11.

I resolved thanks to this thread:

So, the solution to me has been to shut down the computer and then press the Power button during 50 seconds.

Hope this helps.

Roberta
