Abstract
A change is managed in the attachment state between a first device and a second device which are connected via an interface. The first device comprises a high frequency clock. The first device is in a sleep state in which the high frequency clock is deactivated. A detection of a change in the attachment state of the second device is periodically triggered on said interface, on the basis of a low frequency clock. Upon detection of a change in the attachment state, the sleep mode is exited by activating the high frequency clock.
