What about devices that don't have device nodes?  For instance, devices 
with no drivers bound?

Or are you referring to some sort of device node I'm not aware of?

In any case, it's handy to have /proc/bus/usb/devices around.  It contains 
information not found in sysfs, like non-active configurations and 
altsettings and the device's current speed.  It also presents this 
information in a compact, easy-to-read form -- unlike sysfs where all the 
pieces are spread out over many files or lsusb whose output is 
not compact.
