Method and system for controlling operation of interconnected devices by circulating host capability without a centralized manager

摘要

Systems and methods for automatically and controlling operation of one or more devices in a system are provided. In a particular embodiment, a command is received by a device in order for the device to determine whether to perform an operation (such as perform initialization of the device). The command may include information indicative of resource capabilities of at least a part of the system. Using the information, the device may determine whether to begin performing the operation (such as initialization), and perform the operation if it is determined to do so.

1. A method of operation of a device configured to receive power from a host device, the method performed by the device comprising:
receiving a communication via a device communication interface, the communication including information; responsive to a command from the host device to perform an operation, determining based on the information whether or not to perform the operation, wherein the information indicates host capabilities to supply the device with power for performing the operation; in response to determining to perform the operation:
performing the operation;modifying the information, the modified information reflecting power used in the performance of the operation;sending the modified information to the host device or other device powered by the host device; and in response to determining not to perform the operation in the command:
sending the information to the host device or the other device.
