Volker Ruppert 3986a0b703 Extended status bar LED feature to support dynamic indicators for removable 
devices like USB disk, cdrom or floppy. Using this feature for the new USB
floppy. Removed static indicators for port activity from the USB HC code.
TODO: Implement status LEDs for USB disk and cdrom.
