[QUOTE="ngrcarlos, post: 291830, member: 17657"] no sera la mejor respuesta, pero se que se puede sacar solo 5 volts Pinout _________ l_4_3_2_1_l ______ l 1 2l l l l_3___4l Series "A" plugs are used towards the host system and series "B" plugs are used towards the USB device. Pin Name Description 1 VBUS +5 VDC 2 D- Data - 3 D+ Data + 4 GND Ground Features: * True Plug'n'Play. * Hot plug and unplug * Low cost * Easy of use * 127 physical devices * Low cost cables and connectors Bandwidth: * High speed: 480 Mbps speed (in USB 2.0 and above) * Full speed: 12 Mbps speed (requires shielded cable) * Low speed: 1.5 Mbps speed (non-shielded cable) Definitions: USB Host = The computer, only one host per USB system. USB Device = A hub or a Function. Power usage: Bus-powered hubs: Draw Max 100 mA at power up and 500 mA normally. Self-powered hubs: Draw Max 100 mA, must supply 500 mA to each port. Low power, bus-powered functions: Draw Max 100 mA. High power, bus-powered functions: Self-powered hubs: Draw Max 100 mA, must supply 500 mA to each port. Self-powered functions: Draw Max 100 mA. Suspended device: Max 0.5 mA [edit] Voltage: * Supplied voltage by a host or a powered hub ports is between 4.75 V and 5.25 V. * Maximum voltage drop for bus-powered hubs is 0.35 V from it's host or hub to the hubs output port. * All hubs and functions must be able to send configuration data at 4.4 V, but only low-power functions need to be working at this voltage. * Normal operational voltage for functions is minimum 4.75 V. Shielding: Shield should only be connected to Ground at the host. No device should connect Shield to Ground. Cable: Shielded: * Data: 28 AWG twisted * Power: 28 AWG - 20 AWG non-twisted Non-shielded: * Data: 28 AWG non-twisted * Power: 28 AWG - 20 AWG non-twisted Power Gauge Max length 28 0.81 m 26 1.31 m 24 2.08 m 22 3.33 m 20 5.00 m Cable colors: Pin Name Cable color Description 1 VBUS Red +5 VDC 2 D- White Data - 3 D+ Green Data + 4 GND Black Ground si lo quieres ver mejor aqui esta el lnk hacia el "harwarebook" :arrow: http://www.hardwarebook.info/Universal_Serial_Bus_(USB) y aqui tienes un explicacion muy detallada de la historia y funcionamiento del usb :arrow: [url]http://www.zator.com/Hardware/H2_5_3.htm[/url] esperoque te sirva la info!
