Scanner gives a power-up 
beep after scanning a USB 
Device Type.

Communication with the bus must be established 
before the scanner can operate at the highest 
power level.

This power-up beep occurs 

more than once.

The USB bus may put the scanner in a state where 
power to the scanner is cycled on and off more than 
once. This is normal and usually happens when the 
PC cold boots.
