About Powered usb cable:
· PoweredUSB cable provides a single cable connection that supplies both the standard USB communication signals and two additional wire pairs for extra power.
· The design of Powered USB cable and it’s connectors allow for hot-plugging.
· This combined with Plug-and-Play operating systems allows Powered USB cable to be easily maintained and supported in the retail environment.
· One of the limitations of standard USB is the amount of +5V current available to supply attached peripherals. Normally, 500mA is available at each host port and each powered external hub port. It is also have +12V,+24V version.
· This amount of current is sufficient for most PC type peripherals like mice and keyboards.
· When the power requirements exceed the 500mA limitation, external peripherals require the use of an external power supply (brick) to supply the necessary power requirements.
· This limitation takes away from the true "Plug-and-Play" idea conceived for USB peripherals
