The cables of a USB 3.0 will also tend to be slightly thicker because of having more wires inside it, and can only reach 3 meters to be effective.

A USB 2.0 can only have as many as 4 or 5, but a USB 3.0 has 9. One chip solution One possible solution for transitioning a USB 2.0 OTG product that uses a micro-A/B receptacle to a Type-C receptacle is the Texas Instruments TUSB32x product line. For a product that only supports USB 2.0, support for V CONN is not required.
This cable intended to use for host-to-host connection, such as for operating system debugging.įor such applications, the wiring (Table 1) will be: USB 3.1 signal conditioning device within the cable. USB 3.0 specification lists only one wire connection for USB 3.0 Standard-A Male to USB 3.0 Standard-A Male cable assembly.
