The written USB 3.0 specification was released by Intel and its partners in August 2008. The first USB 3.0 controller chips were sampled by NEC in May 2009, [4] and the first products using the USB 3.0 specification arrived in January 2010. [5] USB 3.0 connectors are generally backward compatible, but include new wiring and full-duplex operation.
Ethernet over USB is the use of a USB link as a part of an Ethernet network, resulting in an Ethernet connection over USB (instead of e.g. PCI or PCIe).. USB over Ethernet (also called USB over Network or USB over IP) is a system to share USB-based devices over Ethernet, Wi-Fi, or the Internet, allowing access to devices over a network.
For example, if a USB 1.1 device is connected to a port on a USB 2.0 hub, then the TT would automatically recognize and translate the USB 1.1 signals to USB 2.0 on the uplink. However, the default design is that all lower-standard devices share the same transaction translator and thus create a bottleneck, a configuration known as the single ...
USB communications device class (or USB CDC) is a composite Universal Serial Bus device class. The communications device class is used for computer networking devices akin to a network card , providing an interface for transmitting Ethernet or ATM frames onto some physical media.
As of 2013, Media Agnostic USB (MA USB) is a specification being developed by the USB Implementers Forum. It is intended to enable communication using the Universal Serial Bus (USB) protocol to be performed over a wide range of physical communication media, including WiFi and WiGig wireless networks.

Because voice mode is not the typical use for a modem, many modems on the market have poor or buggy support for their voice modes. Characteristics of a good voice modem depend greatly upon the intended application, and include: Reliable operation. Many modems simply "lock up" or crash the host PC, though this is more common with Winmodems ...
The interface class is used when a USB device can contain more than one function. It is possible, therefore, to have USB devices with two different interfaces at the same time (for example, a USB telephone may use a keypad covered by the HID class and a speaker covered by the USB communications device class).
USB 3.2 Gen 2x1 – newly marketed as SuperSpeed USB 10 Gbps (replaces SuperSpeed+ or SS+), [63] 10 Gbit/s signaling rate over 1 lane using 128b/132b encoding (raw data rate: 1212 MB/s); replaces USB 3.1 Gen 2. USB 3.2 Gen 1x2 – new, 10 Gbit/s signaling rate over 2 lanes using 8b/10b encoding (raw data rate: 1000 MB/s).
