spnav_open() always returns 0 #3

Closed tkelestemur closed 5 years ago

No matter if the SpaceNavigator is connected or not, the spnav_open() function always returns 0. It should return -1 when it's connected, right?

I'm on Ubuntu 16.04.

Are you using the latest version of libspnav? The first thing spnav_open does is check if it's already connected and return -1 if so.

Edit: oh I'm sorry, are you talking about the device itself being present? No, that doesn't have anything to do with spnav connecting to spacenavd. You can connect without a device plugged, and will start receiving events when the device becomes available.

Being able to query the daemon about the device it's talking to, like if it's actually there, which one is it, and how many buttons it has, is a feature high in my list of things to do before releasing the next version.

I'm closing this issue, since this is not really a bug. If you care about the protocol extensions for querying device properties, please open a feature request for that.
