Any cable with a receptacle (except the special case above) or with two "A" or two "B" connectors is, by 9L0-509 definition, not USB.[6] However, many cable manufacturers make and sell USB-compatible (yet not strictly conforming) extension cables with a Standard-A plug on one end and Standard-A receptacle on the other end. Note that these non-conforming extension cables should not be mixed with conforming cables 9L0-402 dumps that contain a small bus-powered hub. Cables with two type A or even two type B plugs are available from more specialist suppliers.
Note that only "full-speed" and "hi-speed" devices use detachable cables. Compliant "Low-speed" devices 9L0-509 only use captive cables, because the low-speed specification does not allow for the electrical characteristics of standard detachable USB cables.
The Mini-B, Micro-A, Micro-B, and Micro-AB connectors are used for smaller devices such as PDAs, mobile phones Testking 9L0-402 or digital cameras. The Standard-A plug is approximately 4 by 12 mm, the Standard-B approximately 7 by 8 mm, and the Micro-A and Micro-B plugs approximately 2 by 7 mm.
