What is the Serial # of the device?
It should be located on the end of the cable, near the USB plug, or on the underside of the device.
Could you send us a copy of the Setupapi.log file?
It should be located in the C:\Windows folder
Have you tried the device on another system?
Are you plugging in directly to the system, or are you using a hub?
Have you tried isolating the device on the USB ports?
Have you tried turn off any kind of power save feature for your USB ports?
In the "Device Manager" you can right click the "USB Hub"(s), that show, and then select properties. On the power management tab, uncheck the box that allows the computer to turn off the USB port to save power (i.e. uncheck the box). Sometimes that has an impact on the connectivity of the devices.
Could you attach a screen shot of your Device Manager (showing USB), and tracking screen (TrackIR software -> View -> Tracking)?
To make Print Screen work, you must save an image of what's displayed on-screen to the clipboard and then paste it into a document where it can be printed.
