some applications of our product we need to override
the class driver with our own vendor-specific driver.

There isn't any equivalent I can think of. You can go looking around inside /System/Library/Extensions to see what kexts (drivers) are available. To remove or update drivers you can delete or install a new kext, not forgetting to touch the folder so the system recaches things at next boot. This would normally be done by an installer ap.

From the terminal "man -k kext" will give you the list of commands which manipulate loaded kexts.

USB Prober will give you a lot of information about USB devices currently attached. It'll also list loaded kexts.

Also the ioreg command from the terminal or the IORegistryExplorer application will tell you what the registry thinks. The Mac registry is not like the Windows regisrty in that its built dynamically, and doesn't store stale information. (At least not across boots.)

IORegistryExplorer and USB Prober come with the developer kit, which if you haven't already, you should install. You should either get a CD with it on or find the installer tucked away in the Applications folder somewhere. Such things are available from the developer website <http://developer.apple.com>, which is a useful resource for everything developerish.

USB, it's not a Dyslexic BUS. (Thanks to TC.)
