Hi, pressed a bit usb cable end did same on tobii input, it worked just for this day. but next day it become broken again. just to say, eyetracker was not moved, or detached lots of time, it was attached to PC once device bin received, and was not moved till it become unresponsive.
as you did not response correctly what i should do to at this point, i just ordered new usb wire to exclude faulty wire. after this i was thinking to bring device to some work shop, to check the device output and resolder the input. but while you suggest to contact tobii tech service i will do that after checking with new wire…
