Tobii EyeX and Expresscard/34 USB3

[Guillaume Spalla]

Dear all,

I have an issue using the Tobii EyeX.
I use a laptop with USB2.0, so I have added an extra ExpressCard/34 to support USB3. I use the following card from Manhattan: http://www.manhattan-products.com/superspeed-usb-expresscard-34
It uses a driver from Renesas, version 2.1.39.0.

My Tobii EyeX runs the firmware 1.8.2-33290.

When I connect the eye tracker, it is correctly detected, however, as soon as I start the calibration, I get the following error message: “Calibration Error – Please check that your eye tracker is plugged and retry”.

Although I did not identify yet what can be the issue, according to what I have seen in this forum, it seems the Renesas driver can be unstable due to the large amount of data the Tobii sends to the PC. Unfortunately according to this webpage: http://plugable.com/drivers/renesas, I cannot get a newer version for this driver, as the chip inside the ExpressCard is too old.

Can anyone confirm this issue with this Renesas driver? Or can it come from somewhere else?
If yes, what is the best solution? To buy a new ExpressCard? I have seen on the support page some advice for internal PCIe cards, but not for ExpressCard. Is there a known compatible one?

Thanks in advance,
Best regards,

Guillaume

Dear all,

Ok I solved the issue, thanks to this post: http://developer.tobii.com/community/forums/topic/how-beefy-should-a-network-host-for-the-gaze-sdk-be/

The issue was that I was not giving the extra power to the ExpressCard. With the extra power, it seems to work perfectly (although some other posts are saying that there is a bandwidth issue with the embedded chip of this ExpressCard).

Best regards,

Guillaume

Thank Guillaume for sharing this.
Finding ExpressCards which actually work, is quite complicated.

Have fun!
