Nothing's going to fail or crash, no conflict or error message will occur. But you'll often get glitches in the audio. CubaseFAQ page www.laurencepayne.co.uk/CubaseFAQ.htm |

This is a machine running Windows XP (or Windows 2K)? XP Pro SP1A This is how Windows XP and its ACPI feature does it. On a desktop machine you can install Windows without ACPI and move cards into different pci slots. On a laptop, ACPI is best left alone, if you want any battery life at all. And, obviously, cards can't be used. So, basically, bummer ;-( I don't care about battery life. If you are able to disable un-used devices in BIOS, do so. Then uninstall the Firewire device from Device Manager and re-boot. If you're lucky, it might move to a better IRQ. But, if not, bummer again. I'm afraid this is one of the several reasons why no-one who doesn't HAVE to should choose a laptop for serious audio or video work. The ACPI thing is discussed on my CubaseFAQ page. The problem isn't confined to Cubase users. www.laurencepayne.co.uk.\CubaseFAQ.htm Thanks for the link. |

Maybe folks aren't bothering to read the entire thread but my problem is the firewire device going offline and only rebooting fixes it. (Hot-plugging does nothing) |
