First, I want to thank you very much for providing that driver, because both EyeX and fwupgrade recognize the Tobii REX, now! However, running the fwupgrade command now returns this:

“Tobii Firmware Upgrade Tool
Automatically selected eye tracker tet-tcp://
Valid Tobii package for g5
Package mismatch”

According to the Gaze SDK tools documentation, this means that the firmware is incompatible with my device. However, I downloaded the only firmware for the REX I could find on http://developer.tobii.com/downloads/ (1.2.4 for USB-HID). Is there another firmware I should be using instead? If it helps, the REX is currently using firmware version

Just for completion’s sake, I also tried upgrading the firmware using EyeX, but it states, “It seems that the eye tracker is not plugged in. Make sure it is plugged in during the whole upgrade process,” even though the REX remains plugged in the whole time.

Thank you.
