Eye TV Tuner will not operate

by jmbklj / July 3, 2009 2:39 AM PDT

I'm new to Mac. Two weeks ago I bought a new iMac (24" 2.66 Ghz Mac OS X 10.5.7) at the Apple store along with the Elgato Eye TV Hybrid tuner. I use the TV function every day, but today it shut off and will not work. I received an error message telling me that Eye TV will not work in a 1.1 USB port and that I should plug the TV tuner in a 2.0 USB port. It's my understanding that all the iMac ports are 2.0.

I tried calling Apple Care Support but they are closed for the 3 day holiday. : (

Any idea what the problem is or what I can do to get this to work? I am using the cables that came with they Eye TV tuner. I've restarted the iMac a couple times and the same thing happens.

USB 2.0

Yes, you are correct. All USB ports on new Macs are USB 2.0 with the exception of the one on the keyboard, which is still, I believe, USB 1.0

Is your device plugged into a USB hub or is it plugged directly into the back of the Mac?

Is the device seen in the System Profiler? Kinda like the Device Manager on Windows. Under the Apple at the top left of the screen. Choose About this Mac and then choose More Info from the next window.
Check under USB to see if you see the device and that the bus is described as Hi-Speed.

If not, try this. Shut down the Mac. Remove ALL the cables from the back of the thing. Power, USB, Ethernet, Firewire.
Leave the thing for 15 minutes.
Plug the keyboard and mouse in, then the Power cord and fire it up.
See if you Eye TV functions now.

Let us know

I tried unplugging the tv tuner several times, trying different ports on the back of the Mac. The Live TV function sometimes works for 5 minutes and then I get the error message or it won't work at all and I immediately get the message. I haven't tried unplugging everything yet, Will try that next.

iMac 2.0 USB port

Well, I shut down the computer and unplugged everything, waited 20 minutes, plugged it all back in and turned it on. So far, so good - it's working! It's been working about 15 minutes now.

Thank you!

Back to not working-recognizing the 2.0 USB port

I went out of town for a week on a business trip......shut down my new iMac, and when I came home, I found out I'm back to the same problem. I called Apple Support and they told me they can't help me with this problem even tho I bought this TV tuner at the same time I bought my new iMac last month at the Apple store.

I uninstalled & reinstalled the software & made sure I have all the software updates.

I found 5 possible solutions for this problem on the Elgato support web gased and so far, I've tried 4 of the 5 fixes with no success. The 5th one sounds technical to me, telling me to reset the PRAM. I don't understand what that entails, so I thought I might run it by the Apple Support people before doing so.

On my previous Media Center PC I used the TV function every day. One reason why I recently bought a Mac is because I was led to believe I would not have problems with it. Unfortunately, in just my 1st month of ownership, I've had nothing but problems with this.

Strictly speaking, you are having a problem with the Elgato device and not with the iMac. This is why the Apple support people told you that they cannot/will not help you.

Resetting the PRAM is no big deal. Follow the instructions below and you are ready to go. I assume that you tried the technique that you went through earlier in this thread?

Resetting PRAM and NVRAM
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
