USB 3.0 Adoption Agreement USB 3.0 Adoption Agreement (.pdf file format, size 146 KB)The USB 3.0 Adoption Agreement allows a signatory company to participate in a reciprocal, royalty-free license agreement for compliant products. This Agreement applies to the USB 3.0, USB 3.1, and USB 3.2 specifications, including the USB Power Delivery and USB Type-CTM Cable and Connector specifications. Any USB 3.0 User Agreement is only effective if it is entered into within one (1) year of the first sale of products containing „Compliant Products“. For more information, see the CONTRACT FOR USB 3.0 USERS. For a product developer, the use of USB requires the implementation of a complex protocol and involves a „smart“ controller in the device. Developers of USB devices intended for public sale should usually receive a USB ID that requires them to pay a fee to the USB Implementers forum. Developers of products using the USB specification must sign an agreement with the Implementers Forum. Using USB logos on the product requires an annual fee and membership in the organization.  Question: I am using ChromeOS and the image on the external display is not consistent/cut. Answer: In this case, it is a problem of insufficient processor. In most cases, laptops with ChromeOS do not have sufficient processors, and DisplayLink software only uses the processor for calculations.
USB4 is based on the Thunderbolt 3 protocol specification.  It supports 40 Gbps throughput, is compatible with Thunderbolt 3, and is backward compatible with USB 3.2 and USB 2.0.   The architecture defines a method of dynamically sharing a single high-speed link with multiple terminal types that best transmits data by type and application. . USB 1.0 was released in January 1996 and specified data rates of 1.5 Mbit/s (Low Bandwidth or Low Speed) and 12 Mbit/s (Full Speed).  Extension cords or pass through monitors were not permitted due to time and power constraints. Few USB devices entered the market until the release of USB 1.1 in August 1998. USB 1.1 was the first revision that was widely released and led to what Microsoft called „legacy free PC.“    A group of seven companies began developing USB: Compaq, DEC, IBM, Intel, Microsoft, NEC and Nortel in 1994.  The goal was to fundamentally facilitate the connection of external devices to PCs by replacing the multitude of connections on the back of PCs, addressing problems with the use of existing interfaces, simplifying the software configuration of all USB-connected devices, and enabling higher data rates for external devices.
Ajay Bhatt and his team worked on the standard at Intel;   The first integrated circuits that support USB were produced by Intel in 1995.  The first main difference is appearance. USB 3.0 is rectangular, most often with blue plastic use (but may vary from manufacturer to manufacturer). USB-C and Thunderbolt 3 have an oval shape. Thunderbolt 3 is marked with the logo of a flash. The USB-C port has no specific rules and can be marked in different ways (depending on the specific characteristics of the port) or must not bear any markings. . . .
