USB 4Gb construction usb data transfer cable homemade

Universal Serial Bus is a high speed connectivity standard enabling
simple Plug and Play connections to devices such as modems, digital
cameras, camcorders, keyboards and mice. The standard is being
supported by many leading suppliers of computers and peripherals.
An advantage of USB is that the devices are hot pluggable meaning
live connection/disconnection without data loss or interruption.
Devices manufactured to the current USB Revision 2.0 specification
are backward compatible with version 1.1.
The USB specification requires a host system to be equipped with
an A type jack. The B type jack is typically found on peripheral
devices requiring detachable cables. Therefore, detachable USB
cables are configured as A to B male combination, preventing
improper bus configurations and topology miswiring.
