Abstract (en)
[origin: WO2014051651A1] A host device can download a firmware update to a peripheral device having previously enumerated with the host device. The host device can perform link training with the peripheral device in response to a re-enumeration indication received from the peripheral device. The link training can include switching a Link Training and Status State Machine (LTSSM) in the host device from an active state (U0) to an RX. Detect state and synchronizing with the peripheral device in the RX.Detect state. The host device can re-enumerate with the peripheral device utilizing the firmware update after the host device completes link training with the peripheral device.
