Hi @crimsonnight and sorry to hear about your connectivity issues. Certainly we provide a list of Support (and tested) USB3 Controllers for the EyeX @
https://help.tobii.com/hc/en-us/articles/209529749-Recommended-USB-3-0-Controllers
Could you kindly provide us the exact models you are using and I can check with the development team if there is anything that can be configured on your end to mitigate this disconnection issue.
Also if possible, try connecting via a powered 3.0 game hub and please ensure the USB3 Drivers are the latest version.
Thanks for your patience whilst we try to resolve the problem. I assume you are running the latest firmware on the EyeX and the latest Tobii Core Software versions?
