Abstract
A method of enumerating a peripheral device preferably includes initiating operation of the device in a low-power mode. Power can be conserved, for instance, by slowing processor speed or by shutting off clocks to one or more unneeded blocks of the peripheral device during enumeration. During enumeration, a host computer preferably obtains enumeration information from the peripheral device and then uses that information to select a configuration state for operating the device following enumeration.
