Nick, I'm gonna have my friend look at your situation because my Windows Vista installation is not asking me for drivers (no pop-up Windows or configuration Wizards appearing), again, the only way I detected the "No drivers installed" was because I did a right click on the MSBus after installing the chipset driver.
It is to my understanding that if no error messages appear, no pop-ups or conflicts in the device manager, then the device, from a software perspective is operating perfectly.
I'll keep you update once I hear back from him.
