In a state negotiation method of a PCI-E upstream device supporting multiple downstream configurations, a state of a second link asserted by a second state machine of the PCI-E upstream device is detected when a first link asserted by a first state machine of the PCI-E upstream device is ready to change from a first state to a second state in a specified duration. A negotiating procedure is performed to have the first link and the second link enter the second state simultaneously if the second link is detected to be in the first state within the specified duration.
