I've recently installed Windows 8.1 on my new ThinkPad x240 and I've been looking for certain missing drivers ... Those devices are marked as "Unknown" by the device manager and the drivers are most probably not downloadable from the lenovo driver matrix (because I downloaded & installed all relevant). The Lenovo Solution Center nor the System Update can find anything ...
The hardware IDs are as follows:
Do you know, what kind of hardware that might be and where can I get the drivers? Thank you!
Solved! Go to Solution.

Unsure about the first device.
Second device appears like it might be the iSCT ACPI Virtual Device.
Third device appears to be the Intel Collaborative Processor Performance Control Driver.
Fourth device appears to be the Intel Dynamic Platform & Thermal Framework Driver.
Fifth deviceappears to be Realtek RTS522x PCIE Card Reader Driver.
Since none of these drivers are specifically for your model of ThinkPad, and appear to be for Windows 8.0, not 8.1, I would advise some caution when installing them. At the very least, perform a backup of any valuable data
Alternatively, wait until Lenovo officially releases Windows 8.1 compatible computers and begins supporting it, and then install the drivers qualified for your operating system.

I guess we will have to wait until Windows 8.1 is generally available, then, for the remaining drivers to become available.

Is part of the Fingerprint Reader, for which the driver is apparantly not installed via the System Update utility. You have to manually install the corresponding driver.

This device is the Validity Finger Print Scanner. To the best of my knowledge and experience with this particuly driver it can't be injected successfully with just the .INF(s) I've found it is best to just install the device driver with the supplied Setup.exe.
The same driver supports many models, but i would always acquire the driver for the model I'm applying it to anyway to ensure the latest supported version.
