Probably it was important to mention that I use USB3 on convertible tablet.

I checked every thing on my both systems and I have full control like you pictures but without success.
I decided to uninstall driver, to remove these two files from ...\drivers. I did this but the files were missed from C:/Windows/System32/drivers WTF. I found them in C:\Windows\System32\DriverStore\FileRepository... copied them and paste in C:/Windows/System32/drivers. No effect
Every time after reinstall the USB driver massage (install new usb driver) was appearing on taskbar. This shouldn't be happend.
When I checked for first time the files grmn**.sys have been there. Some *.exe was putted there.
Several attempts and 4 hours.
Clear all and again. Start from old version 2.3.0.0. The files is appear on C:/Windows/System32/drivers.
Check every thing that you was recomended me, NO PROBLEM
Connect SP II on USB2-mini and YES, YES, YES "Houston we have contact"
On pic can see some changes in course of reinstall.

I would say a BIG THANK YOU. You show me that it's possible to connect SPII with WIN8.1 and motivate me to keep trying.
