Windows 7: Tuner not available after hibernate

09 Nov 2009   #1

Windows 7 Home Premium, 64bit
Tuner not available after hibernate

Hello all,
I recently installed Win7 64 bit and set up MC. I have a USB tuner (HDTV PCTV 800e), and I get "tuner not available or in use by another program" when the PC wakes up from hibernating.

Does anyone know how to fix this? I tried to edit the registry to force a hardware reset on the USB controller per technet, but it didn't work.

I have to reboot the PC to get the tuner working again, something I can't do when I'm not home and the PC wakes up to record TV.

Your hardware (motherboard/BIOS) may not support hibernation (review this with the manufacturer's doucumentation), and/or:

Click Start Orb > type Device Manager in searchbox
Click Device Manager in search results
Expand Your USB Device> right-click on your device > click Properties
Click Power Management tab
Uncheck Allow this device to wake the computer
Uncheck Allow the computer to turn off this device to save power
Click OK
You can also change the power settings and turn hibernation off/ try sleep.
Sleep and hibernation are not the same and are not supported on all hardware.

Thanks, but there is no power management tab under device properties.

I think I changed the settings in power schemes to never shut off USB devices, but I still have the issue. Not sure if that would remove the power management tab under the USB device properties... Well, probably not as my USB remote IR sensor has a power mgmt tab.

I was thinking of getting a powered USB hub, or just getting a PCIe tuner card. Was hoping to use my existing hardware tho.

Thanks again,

USB Device Power Management

Did you review:

"You can also change the power settings and turn hibernation off/ try sleep.
Sleep and hibernation are not the same and are not supported on all hardware."

Also, I am fairly confident that a USB Device would have it's power managed by Windows. "Your USB Device" should appear under "Sound Video and Game Controllers" (expand it and right click your device).

If you cannot find the power management tab for this USB device, I would consult the manufacturer.

The power setting for USB selective suspend is for USB hub power, and simply prevents a power down request from some CPU's to be allowed or not. Some motherboard/CPU combinations handle USB power well (when entering and exiting sleep), some do not, which is when you want Windows to manage it, but some devices also will not work properly with either, or at least are poorly designed for such.

Which Power Setting are you using in Windows? High, low, balanced?

What sleep states does your CPU support? S1, S3 etc. ?


Microsoft Touts Power Management in Windows 7 --

...and run the utility noted.

This all matters...

Thanks, I'll review that article and check out the utility.
I have S3 enabled in BIOS and am using the balanced power scheme.

I'll review my BIOS for any other USB settings. My mobo is a Gigabyte GA-965P-DS3.

Thanks again,

Any lucky with this?

I recently updated my system from XP pro to w7. And when returning from hibernation I hear the standard usb unplugged/plugged-in sound. This results in any program using the usb devices before hibernation needing to be restarted in order for them to work. Very annoying.

Oddly enough it doesn't happen returning from standby. But I cannot use standby exclusively.

No luck. I need to reboot or unplug the USB tuner before it starts working again.
I've been leaving the PC on all the time, something I'm not happy doing.

What does "no luck" mean??


Perhaps you have forgotten that we have also discussed your issue(s) in this thread:

Please review my posts there and reply (somewhere) with:

Please document for us the steps you have taken. The statement "no luck" gives us no feedback or anything to go on.

You also have not provided the requested screenshots. I assume that is because you have your own opinion on how to fix the problem, or, just don't want to bother providing any useful feedback.

We have not ruled out a system problem with hardware. Software runs ON hardware. Most continuing software issues on PC's are due to faulty, poorly designed, or incompatible hardware. In your case you are experiencing multiple issues that in my opinion as an highly experienced hardware designer are hardware related.

If you would provide the screenshots and good feedback, perhaps we can get some things accomplished and continue. This is not just for your benefit. As this is a public forum, we can help others with the same or similar issues by documenting here the steps taken to correct the problem(s).
