I have used Terratec Cinergy Hybrid T USB XS for years now, alongside with Elgato EyeTV software. I am a happy and completely satisfied user!

Since a couple of weeks the USB sitck stopped working on my MacPro1,1 (OS version 10.6.3): EyeTV does not see any device attached, and actually, the green led on the stick stays off.

1. It is not a USB port fault: I have unplugged any other USB/Firewire device and tried with different USB ports, to no avail (any other USB devices work as expected on any port)

2. I have completely uninstalled EyeTV software, including preferences and system daemons/extensions, rebooted and reinstalled the latest EyeTV. No way.

3. Reset the PRAM. Nope.

4. Checked the Apple System Profiler -> USB: No device attached, The MacPro does not see it at all.

I need to say that:

• a) The device worked as a charm even with the latest OS 10.6.x (so it's not a OS upgrade cause).

• b) I have plugged the Terratec Cinergy Hybrid T USB XS to my MacBook5,1 where EyeTV is not installed and was never installed: The green led on the stick turns on, the growl bubble pops up, and the device is perfectly recognized by the system. Apple System Profiler says (sorry, Italian language):

  Cinergy Hybrid T USB XS (2882):
  
  
   ID prodotto: 0x005e
   ID fornitore: 0x0ccd

At this point I am pretty sure the Terratec stick is not damaged and there is something wrong with my MacPro.

I kindly ask you: Is there a way to force my MacPro recognize the USB device? What can I check? Is there something that caches USB connection that can be reset? A OS reinstall would be the very last resort for me.

Thanks in advance for any help you will offer!
