[long, detailed, and readable description] Sounds positively beautiful! Will the driver tolerate devices with identical names, if you have some other app-specific way of telling them apart? That is, if I had two devices connected with your code, both named "Foo," would they show up in enumeration as "Device #1: Foo" and "Device #2: Foo," or would there be a conflict? Or to put it another way - does it require device serialization or merely recommend it? -- Timothy J.
