The connectors the USB committee specifies support a number of USB’s underlying goals, and reflect lessons learned from the many connectors the computer industry has used. Archived from the original on 23 April A high-powered device must be configured, and may only draw as much power as specified in its configuration. On reception of a PRE packet however, it temporarily re-enables the output port to all low speed devices, to allow the host to send a single low speed packet to low speed devices.
