HP Recommended
Product: hp prodesk 600 g4 DM
Operating System: Microsoft Windows 10 (64-bit)

Hello. Not so long ago I got myself great machine HP ProDesk 600 G4 DM with Core i5-8500T. But in Device Manager i see one device that reported by Windows 10 Pro (latest to the date) that there is  UCM-UCSI ACPI Device that has reported problems (Code 43). I updated BIOS from 02.02.04 to 02.09.01 but this did not solved problem. What seems strange to me that during BIOS update process on Front PD USB Type-C firmware update i got error message that newer version firmware is not higher than mine and I had no other option than to press Ok button there, at the same time BIOS and ME firmware was updated flawlesly. Also 02.09.01BIOS readme file says that it contains USB Type-C PD firmware FW 6.8.0, so I gues this should be newer than the one in my PC. Do you have any suggestions what is wrong with that UCM-UCSI ACPI Device, that shows Code 43 error in Device Manager, what its for and how to make it work properly? Tnanks!
