Why then now only 4 stars?
As soon as I had at the beginning inserted more than 2 USB devices (it did not matter what kind of equipment) was a device in the UEFI and also not recognized later under Windows (even the mouse, sometimes the keyboard, printer or sometimes my USB headset)!
A UEFI update brought no improvement.
For -0 Stars (yes times can occur. For this one has the Manufacturer Support!)
So I got me turned to the support from Asrock.
Because after a week still no feedback (auser the best tigungs mail) has come back, I am at Logitech turned (the keyboard is a G15 and the headset is a G35)!
Who gave me back the next day wrote that they know the problem with Asrock, and I still ask the G35 headset and the printer to connect to the keyboard.
Thus, since only 2 devices were plugged directly into the motherboard (keyboard, mouse), the board ran, but the real problem was not fixed!
Shortly thereafter, also Asrock reported via email, with the proposal:
Hello,
Please connect these devices to the USB2 ports (black color) on the rear ports and try again.
Even once disable the BIOS USB LEGACY.
These things I had of course all tried earlier without success!
Of course, I immediately had written back to Asrock, I had already tried everything, and even the Logitech had a better suggestion written to me!
Since no reply came back!
For: -2 Stars (for the real underground Support)
But now indeed a UEFI update has come out, which fixes the bug: +1 Star
To play please only the USB stick and the keyboard plug since bask a device is not recognized in the UEFI may!
Now I can all USB ports to-paste with devices, and I have neither the UEFI still under Windows or Linux problems!
The board runs at last absolutely stable, even when overclocking!
