Hi Matt, There are no options to disable any devices in the BIOS. The AO753 has a webcam (the Sonix entry at ugen1.3) and a SDcard-reader, but nothing else, so there is nothing to unplug. # usbconfig ugen0.1: <EHCI root HUB Intel> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE ugen1.1: <EHCI root HUB Intel> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE ugen0.2: <product 0x0020 vendor 0x8087> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE ugen1.2: <product 0x0020 vendor 0x8087> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE ugen0.3: <USB2.0-CRW Generic> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON ugen1.3: <1.3M WebCam Sonix Technology Co., Ltd.> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON BTW The CPU fan goes to maximum once the kernel is loaded, before probing for any USB devices, not after booting as originally stated. Any more ideas, or any clue on how to further investigate that issue? It's pretty sad, because that computer (although already 2 years old) is pretty much the most powerful machine I have here right now for desktop/mobile use, and it was the one machine destined to run FreeBSD. Still hoping to make it work somehow. Greetings, -- Michael
