Scrambling is implemented using a free-running linear feedback shift register (LFSR).The LFSR is reset whenever a COM symbol is sent or received.

On 28 October 2010, Hewlett-Packard released the HP Envy 17 3D featuring a Renesas USB 3.0 host controller several months before some of their competitors.If there is lack of buffer space or data, it responds with a Not Ready (NRDY) signal to tell the host that it is not able to process the request.When the device is ready, it will send an Endpoint Ready (ERDY) to the host which will then reschedule the transaction.The device either accepts the request or rejects it; if accepted, the device sends data or accepts data from the host.If the endpoint is halted, the device shall respond with a STALL handshake.The structural topology is the same, consisting of a tiered star topology with a root hub at level 0 and hubs at lower levels to provide bus connectivity to devices.

The Super Speed transaction is initiated by the host making a request followed by a response from the device.

AMD worked with Renesas to add its USB 3.0 implementation into its chipsets for its 2011 platforms.

At CES2011, Toshiba unveiled a laptop called "Toshiba Qosmio X500" that included USB 3.0 and Bluetooth 3.0, and Sony released a new series of Sony VAIO laptops that would include USB 3.0.

The available current for low-power (one unit load) Super Speed devices is 150 m A, an increase from the 100 m A defined in USB 2.0.

For high-power Super Speed devices, the limit is six unit loads or 900 m A (4.5 watts), almost twice USB 2.0's 500 m A.

Unlike previous standards, the USB 3.0 standard does not directly specify a maximum cable length, requiring only that all cables meet an electrical specification: for copper cabling with AWG 26 wires, the maximum practical length is 1.3 meters (4.3 ft).
