The
Universal Serial Bus is a connectivity
standard enabling simple Plug and Play
connections to devices such as modems,
digital cameras, keyboards, and mice.
The standard is being supported by many
leading suppliers of computers and peripherals.
The USB specification requires a host
system be equipped with an A type jack
(female). Peripheral devices with permanently
attached cables are to be equipped with
an A type plug (male). This arrangement
prevents improper bus configurations.
The B type connector is for peripheral
devices with detachable cables. Thus
detachable USB cables are configured
as an A-B male to male combination.
Assuming the use of compliant devices,
this prevents topology mis-wiring. With
many customer request, Xmultiple offers
an A-A configured cable.
