Multiple Trackers: EyeTrackerException

[Cassio]

Hey,

I’m using the Gaze SDK and have mutliple Rex connected to my laptop as USB-HID.
Everything works fine at the first startup but afterwards I randomly (at the 2nd or 3rd attempt) get the following Exception when calling tracker.Connect():

An unhandled exception of type 'Tobii.Gaze.Core.EyeTrackerException' occurred in Tobii.Gaze.Core.Net.dll
Additional information: Connection to eye tracker failed. (error code EndpointConnectFailed).

Looks like some resource is still blocked, maybe?

Hi Cassio,
yes, the USB driver has a hard time with client applications that just disappear. You should make sure to disconnect cleanly from the trackers when your application exits to avoid this problem.
