Hi Raf, A copy of the .config would be appreciated. It'll be a few days before I can test it because the board is boxed up ready to cross-ship to ASUS for a replacement. FWIW, I've had the board for a year or so. I learned when I got it that the USB support for the SB600 is bad (based on discussions with the kernel USB mailing list). I worked around that problem with a PCI USB card. Regards, David
