GA-Z170X-UD3 BIOS f6 - Base System Device not recognised

[dodgyb]

Hi,

I am running Win10 x64 and have just upgraded the BIOS for GA-Z170X-UD3 to f6.

The upgraded BIOS resulted in a Base System Device is not being recognised in Device Manager.  The hardware ID's are:

PCI\VEN_8086&DEV_1577&SUBSYS_11112222&REV_03
PCI\VEN_8086&DEV_1577&SUBSYS_11112222
PCI\VEN_8086&DEV_1577&CC_088000
PCI\VEN_8086&DEV_1577&CC_0880

Research indicates that this a Thunderbolt port.

Where can I locate the correct Win10 x64 device driver for this port which will be compatible with BIOS f6?

Thanks

The GA-Z170X-UD3 Support & Downloads page (Download type: Driver; OS: Windows 10 64bit) shows

Thunderbolt Driver version: 15.3.40.275  date: 2016/02/19 That version is listed in the "release notes.txt" file. All of the driver inf files in that installer report the version as 15.3.40.2 date: 2016/01/03

After you install the driver, you need to run the "USB3.1 FW Update Tool" (Download type: Utility)
