LFS should integrate the udev rule above.
The patch is no longer needed with libusb-0.1.12. This version of libusb first tries /dev/bus/usb (where udev creates real device nodes with the above rule) and then falls back to /proc/bus/usb (should not happen with linux >= 2.6.14 with proper udev rules, because /dev/bus/usb is always available). Thus, if all applications requiring raw access to USB devices used libusb, one could remove the /proc/bus/usb mount. Unfortunately, VMware and other proprietary apps beyond BLFS may still need this obsolete mount point because they don't use libusb.
/dev/bus/usb and /proc/bus/usb don't conflict. It's just that udev can't be used to set /proc/bus/usb permissions reliably.
