xHCI mode work for Windows 7 8 10. Specially motherboard have addtion USB 3.0 Chip.
May be need enable via BIOS
Different OS Windows, different Intel Chipset
Check version before download.
00:00 USB 2.0
Old Motherboard only show USB 2.0. But have 2 chip USB 3.0 like AV Media or VIA VL
00:25 Setting USB 3.0
If motherboard not support USB 3.0, but using chipset from AV or VIA.
Must enable from BIOS Motherboard
Go to Peripheral setting
Find xHCI and set Auto
00:44 Save and Reboot
01:00 USB 3.0 Active
You can see from Control Panel, click USB
2 addition from USB table, Intel USB 3.0 eXtensible Host Controller and Intel USB 3.0 Root Hub.
01:15 Free Device Monitoring
Can check via software, if port already active with USB 3.0 connection
Specially older motherboard like Intel don't have USB 3.0
But Motherboard manufacture add USB 3.0 chip controller.
Must set enable from BIOS, setting via xHCI mode Enable or Auto.
Using USB 2.0 only get speed 480Mbits or about 50MB/s
Using USB 3.0 Super Speed get 5Gbits, speed tranfer more than 100MB/s
WIth USB 3.0 suitable hardware tranfer like USB Display via USB 3.0 port
BIOS Setting USB 3.0 xHCI and a few setting
XHCI Mode = Disabled - The on-board USB 3.0 port function like a 2.0 port
XHCI Mode = Enabled - The on-board USB 3.0 port function like a 3.0 port
XHCI Mode = Auto - The on-board USB 3.0 port function like a 2.0 port before OS USB 3.0 driver load. If you reboot the OS, the on-board USB 3.0 port again function like a 2.0 port during this reboot BIOS phase before OS USB 3.0 driver load.
XHCI Mode = Smart Auto - The on-board USB 3.0 port function like a 2.0 port before OS USB 3.0 driver load. If you reboot the OS, during this reboot BIOS phase, BIOS is "Smart" enough to avoid downgrade the USB 3.0 port back to 2.0 functionality before OS USB 3.0 driver load. So Smart Auto is faster than Auto on 2nd boot onward, but Enabled is fastest once you are sure the OS has the USB 3.0 driver installed, because it avoid the switching. Making the on-board USB 3.0 port function like a 2.0 port is mainly to support OS installation or to support OS that does not have build-in USB 3.0 driver, so that the USB keyboard would still work if the user plug-in a USB keyboard or any other USB devices into the USB 3.0 ports before the OS is installed with the USB 3.0 driver come with the motherboard.
