Missing driver (Win10 Pro 64bit) - unknown devices

HP Recommended
HP EliteBook 8560w
Microsoft Windows 10 (64-bit)

After installing Windows 10 Pro 64bit (20H2) I get following non known devices (shown in the device manager found in "other devices")):

- Basissystemgerät (basis device)

- HP hs2340 HSPA+ MobileBroadband

- unbekanntes Gerät (unknown device)




1st device: \_SB.PCI0.RP03.SMHC

2nd device: \_SB.PCI0.EHC2.RHUB.PRT0.HPT1

3rd device: \_SB.PCI0.ACEL

If further information is needed I will provide them (hopefully).


What kind of devices are these (mentioned above)? Which purpose do they have?

Where can I find the neccessary drivers for the devices mentioned above?


Thank you in advance for your help.

For the hs2340 device, install the W8.1 driver in W8.1 compatibility mode.


This driver installer package contains the drivers for the Ericsson HP hs2320/hs2330/lc2000/lc2010/hs2340 Mobile Broadband modules


Here's how to install the driver in compatibility mode...

For the first device in your screenshot, you need this driver...


The JMicron Media Card Reader Driver enables the integrated media card slot in supported notebook models that are running a supported operating system.


The unknown device probably needs this driver...


This package provides the HP 3D DriveGuard software for supported notebook models that are running a supported operating system. HP 3D DriveGuard protects the hard drive by "parking the heads" if the notebook is accidentally dropped or is abruptly impacted by another object.
