Table 4.7-1 below summarizes the USB transfer methods.
Several transfer methods are specified for the USB.
Transfer methods
Isochronous transfer
preferred transfer method
for the USB. This transfer
method has a guaranteed
bandwidth and is used
where real-time transfers
are required, such as audio
equipment, telephones,
etc.

guaranteed, thus
requiring quick
responses. Keyboards,
game pads or consoles
use this transfer
method.
