I have the problem, that i'am only able to logon at the PreBoot Screen, when the USB Devices are disable or the USB Mouse is unplugged. Otherwise, the PreBoot Screen hangs up and i can't do anything. Are there any solutions to fix this problem? I don't want to unplug the mouse at each time i reboot .
doesnt matter which hardware is plugged in on the left side, Keyboard, USB-Stick, Mouse. it works. but similar on the right side. doesnt matter which hardware is plugged in on the right side, the Notebook hangs up on PreBoot Screen after 1-2 Seconds. Your are able to move the Cursor and Type your Password, but after 1,2 Seconds it hangs up.
