THE SOLUTION: To solve this tedious problem i've disabled in the BIOS the "USB 1.1 OHCI Controllers" that prevent the "USB Legacy" option. No devices I have plugged in the USB ports (I've used old PS/2 keyboard and mouse). THE QUESTION: please, can you tell me what this means ? It means the HUB is unable to enumerate some device, because it is not responding correctly to the USB tokens the host controller is sending. But for an hardware problem or maybe the Freebsd kernel does'n support the USB Legacy ? Thanks in advance.
