Michael,
the Elisys Usb Tracker is a very powerfull and cheap device .
Personally I didn't have access to such tools when I started my USB projects.
It can be somewhat difficult to get the enum working at least if this will be your first usb project.

All software tools require a successfull enum of your device at least
- GetDescriptor (Device & Config)
- SetAddress
- SetConfig
requests must be working.

You should also take a look at www.thesycon.de.
They have a very powerfull driver you may check.
They have a demo with source the only limit is the need of rebooting after 20 min .
