You question is unclear.
Since you want your tool not to be based on hardware, I assume that means
you want it to run on the host, not on the device. That means you're
asking about a Linux or Windows device driver of some sort.
On the other hand, what good is such a tool if it doesn't have a USB
device to communicate with? Trying to send a USB transaction won't
accomplish anything if there's no device to receive and reply to the
transaction.
>From one point of view, practically _all_ USB device drivers send specific
transaction data. None of them make up data at random. So any driver
will do what you ask.
But perhaps you have some particular data that you want to send. As far
as I know there aren't any drivers that will let you plug in arbitrary
data and send it for you. However, it's trivial to write a user program
(not even a kernel driver!) that will do this for you, using libusb.
If you're interested in testing a Linux host controller driver, you should
look into usbtest:
