Abstract
A method for port policy management for active charge through of a peripheral device that has a first communication port and a second communication port may include detecting whether a valid power connection exists at the peripheral device, in response to detecting the valid power connection, determining a relationship between the first communication port and the second communication port, based on the relationship, determining, by the peripheral device, a power relationship among the peripheral device, the first communication port, and the second communication port, selectively configuring the first communication port, the second communication port, and the peripheral device to match the power relationship, and enabling active charging through of the peripheral device if active charging through is supported by the power relationship.
