I have an Asus X553MA laptop and have had to reload windows 8.1 Pro. Now I have no driver for the PCI encryption/decryption controller. I have searched every place possible but cannot find the driver. On the Asus web site they have drivers but my device manager indicates they are not the correct ones for this laptop. The device missing drivers is :- PCI\VEN_8086&DEV_0F18&SUBSYS_161D1043&REV_0E\3&11583659&0&D0 was configured but showing no driver. Not sure but I think this controller maybe an Intel Atom processor Z36xxx/z37xxx series trusted execution engine. The laptop processor is an Intel N3540 2.16 cpu
