 /proc/bus/usb filesystem output
 ===============================
-(version 2003.05.30)
+(version 2010.09.13)
 
 
 The usbfs filesystem for USB devices is traditionally mounted at
 /proc/bus/usb.  It provides the /proc/bus/usb/devices file, as well as
 the /proc/bus/usb/BBB/DDD files.
 
+In many modern systems the usbfs filsystem isn't used at all.  Instead
+USB device nodes are created under /dev/usb/ or someplace similar.  The
+"devices" file is available in debugfs, typically as
+/sys/kernel/debug/usb/devices.

 **NOTE**: If /proc/bus/usb appears empty, and a host controller
           driver has been linked, then you need to mount the
