These three bits determine the number of wait states (machine cycles) to 
insert when accessing the USB SFRs: 
000 = 0 (not to be used). 
001 = 1 wait state. Use when MPU clock is <12MHz. 
010 = 2 wait states. Use when MPU clock is between 12 and 16MHz. 
011 = 3 wait states. Use when MPU clock is 24MHz. 
100 = 4 wait states. 
101 = 5 wait states. 
110 = 6 wait states. 
111 = 7 wait states.
