Hi @fitsy, sorry to hear about your issues. There are a few things you can try:
– Attempt a connection via a different USB hub, and ensure that your USB Chipset Drivers are fully up to date
– Are you using a USB hub and/or are you sure to be using a powered USB33 port? Please send your system specs over to check
– Try uninstalling all the Tobii software and device drivers, reboot and reinstall
– Also, worth trying to update your motherboard BIOS and ensure that any USB power saving options are not enabled
– Finally, it may be worth trying on another system if possible to eliminate the possibility of a hardware fault.
Please go through these and let us know how you get on.
