I have the same Problem – “Searching for eye tracker” but not found.
There is a red light blinking on the right side of the tracker, but the Settings tell me “Could not connect to eye tracker”.
The tracker appears as usb device, the Firmware updater says that there is nothing to update.
I tried to update the usb3.0 Driver, but it has also the newest Version.
I am using a PCI connected USB3.0 Card.
