Hi Eric,

That's the one.

I was hoping that the USB printer port would show up as an emulated legacy port.

The only small hope I still have with this is that there is some driver or driver mode for the device that will do this.

Other than that, it'd be a development effort to support a USB printer port I'm sorry to say.

There may be some other options:

1. I think Sigurd KJ1K has built a serial to discrete output interface using a microcontroller.  Not sure if it would be easy to duplicate.

2. Here's something else interesting I found:

Here's the part:

It's a pretty interesting part.  I've not come across it before.

3. I bet there is something else off the shelf for serial to discrete output, but I don't know any off the top of my head.

Anyone else?

Tom.

Do you mean this section?: "On most PCs, 378 is the base address for
LPT1:, but some use different addresses. To find the base address for
your PC's parallel port, visit My
Computer->Properties->Hardware->Device Manager->Ports (COM and LPT).
In the example below, the base address is 3bc. Check this before you
try it. Do not assume the correct address is 378."

The device I have doesn't show up under ports(nor are there any ports
at all under Ports), it shows up under USB controllers. Even then,
there is no I/O range to be found in there, just details about the
USB capabilities of USB0001(power, sleep). This device port USB0001
shows up when I try to add a printer, so I know the OS thinks it's
valid/working.

Thanks,

Eric
