i'm trying to us old cords and usb power etc... I know what is power +
and neg on a USB A. But which is power in and which is power out,
the pos or the neg????

 

I blew that ,,I mean which is DATA in and DATA out........

 

Of the 613,00 hit on Google for "USB pinout", this one seemed to be ok - http://pinouts.ws/usb-pinout.html.

 

There's no data in and data out. They use the same link, which is a differential link D+ and D-. The page beenthere referenced above shows the pinouts.

 

There's no data in and data out.

Look at the attachment.

 

Look at the attachment.

Well... still no.

There are no data in and data out wires. Both D+ and D- form a bidirectional differential signal data link between the host and peripheral, which the direction is protocol controlled by the host.

Please refer to USB standard.

I think what is being said here is that the in out control is a software solution.(traffic control scheme)

 

also what may be in question is do you need a crossover or is d+ tied to d+ and d- to d-.

this was why I wanted to know, note his descrip.

 

Looks to me like you want to know about RS-232 pinout. You might just get a RS-232 to usb adapter. saves the driver problem.
