Everything is working great on my old Z68X Ivy Bridge system with OpenCore v0.6.0 Edit: Subsequent updates through 11.0.1 Release Candidate 2 (build 20B28) installed normally after changing Misc > Security > SecureBootModel to Disabled in my config.plist. Everything continues to work properly...

I was encountering similar issues when upgrading to High Sierra on my GA-Z68X-UD3H-B3. The Clover config.plist posted by vulgo in the post here which uses the iMac 14.2 SMBIOS and includes a number of DSDT fixes cleared up the problem. Attached are all of the kexts I needed on the EFI...

The <Alt> key (not the Windows key) functions as the macOS <Command> key on the X220.

USB 3.0 ports started working properly for me under Sierra 10.10.2 with UEFI BIOS U1n after removing GenericUSBXHCI.kext This is discussed in more detail in the thread here

Onboard USB 3.0 has been working for me with this board under 10.11.5 with GenericUSBXHCI.kext version 1.2.11 placed in EFI:EFI/CLOVER/kexts/Other

It looks like recent El Capitan updates have corrected whatever was going wrong with this mouse. I have 10.11.4 installed and my Lenovo Laser MOBGBO is identified in the system profile as "Lenovo Laser Mouse" and it is working perfectly again.

I put together a guide to install OS X 10.11 El Capitan on the ThinkPad x220 here: http://x220.mcdonnelltech.com/ I don't have an x220 with USB 3.0 so unfortunately I can't address that issue. Hope this helps!

The Inateck KT4006 also works perfectly under OS X Yosemite 10.10.2. Recognized without configuration as a USB 3.0 Hi-Speed / SuperSpeed Bus with my Intel DG33FB motherboard. Plenty of power for every external hard drive I've tried it with. Apparently some other Inateck USB 3.0 PCIe cards...
