Hand-held devices require communication with the notebook PC before they start to draw current. This ensures that the handheld device will obtain sufficient current when it wants to charge. The issue is that the notebook PC does not have a way to provide this acknowledge signal to the handheld device when the notebook is in “Sleep” mode. Pericom’s PI5USB58 solves this issue by setting the D+/D- pins in the notebook PC to the required signal levels during “sleep” mode.
