Please delete line6usb (http://aur.archlinux.org/packages.php?ID=15333), since it's now in the mainstream kernel (/lib/modules/2.6.35-ARCH/kernel/drivers/staging/line6/line6usb.ko). I created a PKGBUILD for the svn version of the driver (http://aur.archlinux.org/packages.php?ID=40604). Cheers, Emman
