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. If the endpoint is halted, the device responds with a STALL handshake. The device either accepts the request or rejects it if accepted, the device sends data or accepts data from the host. The SuperSpeed transaction is initiated by a host request, followed by a response from the device. 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.Дata transfer and synchronization In USBВ 3.0, dual-bus architecture is used to allow both USBВ 2.0 (Full Speed, Low Speed, or High Speed) and USBВ 3.0 (SuperSpeed) operations to take place simultaneously, thus providing backward compatibility. The plastic insert is in the USB 3.0 standard blue color known as Pantone 300C. Architecture and features ДЇront view of a Standard-A USBВ 3.0 connector, showing its front row of four pins for the USBВ 1.x/2.0 backward compatibility, and a second row of five pins for the new USBВ 3.0 connectivity. This gives USBВ 3.0 a potential total bidirectional bandwidth twenty times greater than USB 2.0.

USBВ 3.0 has transmission speeds of up to 5В Gbit/s, about ten times faster than USBВ 2.0 (0.48В Gbit/s) even without considering that USBВ 3.0 is full duplex whereas USBВ 2.0 is half duplex.

Support for rotating mediaВ вЂ“ the bulk protocol is updated with a new feature called Stream Protocol that allows a large number of logical streams within an Endpoint.

Improved bus useВ вЂ“ a new feature is added (using packets NRDY and ERDY) to let a device asynchronously notify the host of its readiness, with no need for polling.

Power managementВ вЂ“ U0 to U3 link power management states are defined.

Increased bandwidthВ вЂ“ USBВ 3.0 uses two unidirectional data paths instead of only one: one to receive data and the other to transmit.

Transfer speedВ вЂ“ USBВ 3.0 adds a new transfer type called SuperSpeed or SS, 5В Gbit/s (electrically, it is more similar to PCI Express 2.0 and SATA than USBВ 2.0).

The changes in this specification make improvements in the following areas: The specification defines a physically separate channel to carry USBВ 3.0 traffic. Earlier USB concepts such as endpoints and the four transfer types (bulk, control, isochronous and interrupt) are preserved but the protocol and electrical interface are different.

The USBВ 3.0 specification is similar to USBВ 2.0, but with many improvements and an alternative implementation.

Nomenclature has been broadly criticized by both experts in the industry and the public at large for its confusing revisions not reasonably or appropriately reflecting the marketing messages that the guidelines prescribe in the standard specification, which is published at usb.org This specification has been renamed to reflect the evolution of 'generations' of USB standards (i.e.: USB3.2Gen1 is 'SuperSpeed', USB3.2Gen2 is also 'SuperSpeed', but 2x faster, USB3.2Gen2x2 is also marketed as 'SuperSpeed' but is 4x faster than 3.2Gen1).

It preserves existing USB 3.1 SuperSpeed and SuperSpeed+ data modes and introduces two new SuperSpeed+ transfer modes over the USB-C connector using two-lane operation, with data rates of 10 and 20 Gbit/s (12 MB/s after encoding overhead). USBВ 3.2, released in September 2017, replaces the USBВ 3.1 standard. USBВ 3.1 preserves the existing SuperSpeed transfer rate, giving it the new label USB 3.1 Gen 1, while defining a new SuperSpeed+ transfer mode, called USB 3.1 Gen 2 which can transfer data at up to 10В Gbit/s over the existing USB3-type-A and USB-C connectors (1200В MB/s after encoding overhead, more than twice the rate of USBВ 3.0). USBВ 3.1, released in July 2013, is the successor standard that replaces the USBВ 3.0 standard. It is recommended that manufacturers distinguish USBВ 3.0 connectors from their USBВ 2.0 counterparts by using blue color for the Standard-A receptacles and plugs, and by the initials SS. Among other improvements, USBВ 3.0 adds the new transfer rate referred to as SuperSpeed USB (SS) that can transfer data at up to 5 Gbit/s (500 MB/s after encoding overhead), which is about 10 times faster than Hi-Speed (maximum for USBВ 2.0 standard).
