Mamba in Synapse 3? + Synapse 2 login issue

Hello guys,
I have a Razer Mamba (think it's the 2015 edition) which currently is only supported by Synapse 2.
Does anyone know when this device will be available in synapse3? I don't think it would be a big deal to copy the device related files to synapse3.. Is there a way to make it compatible by myself?

Until there is a way to use Synapse3 for all my devices, I have to also install Synapse 2. BUt when trying to log in, I get a long loading screen (~5 mins) followed by the error "network not available". The log gives me the following:
[SynapseMain::15476] ERROR Razer.Storage.COPProtocol.COPRequest [(null)] - COP-SEND:failed, cod=Timeout
System.Net.WebException: Timeout für Vorgang überschritten
bei System.Net.HttpWebRequest.GetRequestStream(TransportContext& context)
bei System.Net.HttpWebRequest.GetRequestStream()
bei ..(COPRequest )

Is there a way to fix this error?
