If you remove "device usb", you will also need to remove uhci, ohci, ehci, umass, ukbd, etc. etc. etc... from your config as well. You do not need to disable USB support in the BIOS; the kernel will simply state that it sees devices on the PCI bus but lacks a driver to attach to them. This will not harm anything. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
