General question about driver needs

Hi,

Ok, I am not very familiar with the whole driver development thing, so I just have a general question to make sure I'm going down the right road.

We have a custom USB device, it's a micro-processor with a USB port attached basically. All we want to do is transfer some proprietary data to/from it and perform some other miscellaneous functions.

We can't use anything like a standard memory device which is why it's a processor.

So, does this actually mean I need to write my own drivers to interface our software with it? Or are there drivers in the system that allow for generic access to a USB port?

See? I'm totally new and have no idea what's going on. :blush:

As long as your custom USB device is following the specification of USB, then
you can use generic device driver. Following link may be useful for your

USB Library

Thanks! That looks pretty useful.

Two questions:

With that license, can it be distributed with a commercial app? I really don't understand legal speak.

And,m does it work for Vista?
