When install win10 (1809) on MacBook Pro (Version2019), encounter an error which is "unknown device ACPI\VEN_INT

When

installing Windows 10 on the MacBook Pro, it is installed normally through the

conversion assistant called “Boot Camp”. When win10 is installed successfully,

all the drivers that come with the Boot Camp 6.1 are installed according to the

prompts. But device manager of win10 prompts for "unknown device"

whose hardware ID is "ACPI\VEN_INT&DEV_34BA".  Please!  I want to know what hardware the unknown

device is and how to install its driver?

Information

of the unknown device is shown in the following figure

Thank

you very much!

Best

wishes!
