Unplug the USB sound card. Then boot. After the boot plug in the USB card so that the hot plug picks it up. The configuration might be different enough to allow them to coexist. If plugging in the USB card still displaces the sound card, that is a bug and you should report it. I would guess that would be at your distribution. Actually, even the above behavior is a bug. The hot plug for USB shouldn't be displacing interrupts that have already been assigned. It isn't playing nice. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
