hey ppl
i have a USB web cam. so it it has data+ and data- connections for USB communication
when i tried to give the data+ connection through a buffer (opamp- voltage follower), the computer says "device error". without any buffer, its working fine.
the thing is when i connect through the voltage follower, the voltage output at Data+ terminal of the webcam gets altered !!
why is it so ? voltage follower should suppose to give the same voltage right ??
