I had problems with a usb harddisk, which only worked if plugged in after FreeBSD booted. The computer hang if I plugged it in before or while FreeBSD was booting. After I disabled USB in the BIOS, FreeBSD still found the usb devices, but the computer doesn't hang anymore. So I think I had a conflict between my BIOS and FreeBSD both doing things with usb (or the irq of usb, I don't know). BTW: this only happens with my us harddisk. My usb bluetooth device doesn't have this. You could try this also, but no garanties. Ronald. -- Ronald Klop Amsterdam, The Netherlands
