How do I control voltages to pins of the USB programmatically?
For example, I'd like to say send a signal to individual USB pins (if
that's applicable in USB) how do I do that ?
Also what's the appropriate newsgroup for this question? Thanks .
Think of what USB stands for
Universal
SERIAL
Bus
I'll admit to knowing next to nothing about USB, but there's nothing
inherently wrong with wanting to send a signal to individual pins in a serial
connector. Think about RS232 -- only pins 2 and 3 carry data; 6, 7, 8, and 20,
among others, are used for signaling equipment states.
USB uses 4 wires:
Power to device:
V+
V-
Data between devices:
Data+
Data-
No individual pins to control.
