Hello experts,

Another curiosity where I need your help/advice: When I install Win10 and use Lenovos advised Intel Chipset Device Software (9.3.0.1021), it installs a device called Intel (R) 7 Series/C216 Chipset Family SMBus Host Controller - 1E22:


Then I go on installing some other drivers. After installing Synaptics/Ultranav Touchpad driver the SMBus with DEV_ID 1E22 suddenly gets "hijacked" by Synaptics:


That's weird. VEN_ID 8086 is by Intel - so how can Synaptics Touchpad driver take over this device??

I have to admit that I have never looked into this part of the menu

Here are the results:


But in the end it looks like Synaptics has taken over the Intel device. Or what do you think?

Ok, got it. New to me was the fact, that another manufacturer can take over integral Intel chipset devices and install own drivers for them. Thought it's only allowed for Intel to deliver drivers for their chipset devices. Again what learned.
