Install this driver 
Recently installed Windows 11 on my 5290 2 in 1; after which I immediately installed the only Intel Chipset Device Software,  version 10.1.18121.8164, A09. Dated 25 Mar 2020 All devices except 1 were identified except 1,  Unkown device Hardware id is shown to be "ACPI\VEN_INT&DEV_33D6, ACPI\INT33D6, *INT33D6" Due to the age of the Intel Chipset Device Software I am wondering if there is or should be a newer version???? Looking for a solution; Any ideas?? Thanks Rew    
Unknown device ACPI\VEN_INT&DEV_33D6
