USB 3.0 OTG Port on UP Squared not working - functionality?

Hi All,
yesterday I did a first test of the UP Squared and a fresh Windows 10 Pro installation.
Now I have a question. How is the functionality of the USB OTG Port?
All ports working fine, except the OTG port, perhaps I don't understand the functionality.
I connected the USB3.0 OTG cable from the Up Shop to the Micro-B Port on the Mainboard.
Should the USB3.0 Port from the cable now work in host mode so I can plug in
any USB device (USB-Stick, peripherals)?
Actually if I connect a device (USB Stick) it isn't recognized and nothing happens.
What should I do with the USB A plug at the cable, do I have to plug it into a USB port
for additional power supply?
Or do I have to make BIOS changes/update or install additional drivers to get it work?
Because I still have one problem, in the device manager in windows one device has
missing drivers, it's a not further described USB Controller.
BIOS Situation:
BIOS Version -> R2.1 -> Is it necessary to upgrade to V4.0 and afterwards V4.6?
Are there big improvements or otherwise known problems with this new bios versions?
Software Situation:
Fresh Windows 10 Pro installation.
After that i had 4 missing drivers for devices in Win 10 device manager:
1. Sound-Device -> BIOS settings changed -> fixed
2. Unknown Device -> manual UART driver installation from UP Win 10 Drivers Pack -> fixed
3. Unknown Device -> manual UART driver installation from UP Win 10 Drivers Pack -> fixed
- USB Controller -> no drivers found in UP Win 10 Driver Pack using manual driver selection in Win10 device manager -> not fixed
Are there drivers for the USB Controller somewhere?
Should I additionally install the whole UP Win 10 Driver Pack?
The installed drivers are way more actual as the drivers from the Up Driver Pack,
so I think it's not necessary to install them.
Thank you.

The USB OTG port will only work for host side of the OTG, and USB OTG cable is not supported from an Windows 10
So, you'll need a adapter to link USB OTG port to USB device as the hyperlink below
USB3.0 Adapter Micro B male to A female
About USB Controller, this is USB OTG controller, and no windows driver for this device.
