USB 2.0

Postby musofa81 » Wed Apr 23, 2014 4:18 pm

A USB consists of 4 wires which are Vcc, Ground, Data+ & Data-. I am wondering, can I use either Data+ or Data- as a power source. For instance, to power up an LED for fews second? Thanks in advance for those who shared the knowledge.

Never tried that before, but I guess the signal is too small to turn on LED. Besides, this will definitely disturb the USB communication.
