I'll cut-and-paste it here (in particular read the last sentence); "Q: Why doesn't /proc/bus/usb exist?
A: If you've setup the hotplug scripts it should be there, please report this to the user's mailing list. If you don't want to use those scripts you'll need to add the following line to you're /etc/fstab; none /proc/bus/usb usbdevfs noauto 0 0 And mount this after the usbcore module has been loaded. More information is available in the USB Guide under "USB Device Filesystem". In 2.2 and 2.4 kernels this directory should be created when you load usbcore, however there will be no content till you mount usbfs (which will be the new name for usbdevfs). In 2.5 this directory will remain empty till you load a host controller."
