What the USB specification says it means is that the value is not defined in the device descriptor but in the interface descriptor(s). Putting such a value into an interface descriptor is 1) obviously wrong, 2) violates the USB specification (vendor-specific interfaces must be marked, not surprisingly, as "vendor-specific"), and 3) forces you to match by device vendor/product IDs only. > ... without any luck getting the device to work; after a couple of > reads from the device I would get timeout errors, or after writing all > reads would return a timeout error (which was the exact same behaviour > from the 'old' driver). This would be an indication that your device speaks a completely different protocol.
