In a computer system having a device and a communications link for communicating with the device. A method for dynamically managing power consumption by the computer system comprises associating a particular device identifier with the device. Communications are monitored over the communications link to determine whether the communications include the particular device identifier. A clock input is withheld from the device when the communications do not include the particular device identifier. Clock input is provided to the device only when the communications include the particular device identifier.
