Abstract
Methods, physical computer-readable media, and devices are provided that allow re-enumeration to be initiated on a USB 3.0-compatible device. The method includes establishing a connection with a host, transmitting an indicator from the device to the host to cause a Link Training and Status State Machine (LTSSM) of the host to move from active state (U0) to one of SS.Inactive and RX.Detect, synchronizing the device with the host, and presenting a new configuration of the device to the host.

A method of initiating re-enumeration of a device compatible with USB 3.0, the method comprising:
- establishing a connection with a host;
- transmitting an indicator from the device to the host to cause a Link Training and Status State Machine (LTSSM) of the host to move from active state (U0) to one of SS.Inactive and RX.Detect;
- synchronizing the device with the host;
- and
- presenting a new configuration of the device to the host.
A physical computer-readable medium having stored thereon instructions that, when executed by a controller:
- establish a connection with a host;
- transmit an indicator from a device to the host to cause a Link Training and Status State Machine (LTSSM) of the host to move from active state (U0) to one of SS.Inactive and RX.Detect;
- synchronize the device with the host;
- and
- present a new configuration of the device to the host.
A device comprising:
- a controller;
- and
- a memory in communication with the controller, including instructions, that when executed by the controller:
- establish a connection between a device and a host,
- transmit an indicator from the device to the host to cause a Link Training and Status State Machine (LTSSM) of the host to move from active state (U0) to one of SS.Inactive and RX.Detect,
- synchronize the device with the host, and
- present a new configuration of the device to the host.
