Only one interface can be enabled at time, this indicates which interface is actually used for USB.
Only one interface can be enabled at a time per bInterfaceNumber. When bInterfaceNumber is auto-allocate(0x4) for [[#GetDsEndpoint]] this isn't an issue since the final bInterfaceNumber will be unique.
Once enabled, the device/interface can then actually be used over USB.
