It's so easy to control 8 devices via Parallel Computer Port, I'm looking the same for USB, any links to freeware projects, and software for them are welcome :)

There are not too many ways to do that :( One of the simplest options is to use something like FT232/FT245 from FtdiC*ip and build some support circuitry around them (for example port expanders).

Hi 7rots51,

Can you please post the links for Phi*ips PDIUSBD11/D12 examples/Windows driver? I've visited the Philips site many times and yet I was unable to find these examples.
By the way, I've read a few things about USB devices and it seems that using the FT*I chips is much easier than working with the PDI chips. Nevertheless, the latter are a little more flexible.

Hi Gulson,

Sorry, I forgot to post this in my previous reply. Maybe you're looking for something like this:

This is bcause everey usbdevice needs a driver FTDI has really good
drivers for their devices.
If you make a USB device which is comatible with the HID spec all OS from 98 have HID support included.

Therefore no custom driver needed! Toggling Portpins should be easy with a HID device.
