Hi,
sorry to revive this thread, but I am encountering exactly the same troubles on my Gigabyte P34G v2 with Win 8.1. The tracker does not seem to register that it is connected to a usb3.0 port. I un- and reinstalled the Intel/MS usb 3.0 host driver, un- and reinstalled the eye tribe drivers/sw and I got the tracker connected to the usb 3.0 ports on the laptop. USB3.0 seems to be working fine with usb3.0 flash drives and doesn't throw any errors there.
Any ideas?
Thanks,
Martin
