Windows 7: Error when trying to remove HP TV Tuner

Error when trying to remove HP TV Tuner

Please review my system specs before tailoring your response.

I have an HP USB Digital/Analog TV Tuner device which I use on occasion. When it's plugged in, it works fine. It's getting it out that's the problem.

1) When I use the "eject device" menu from the taskbar, I get a message popup:
Windows can't stop your 'HP Digital/Analog TV Tuner (Analog)' device
because a program is still using it. Close any programs that might be
using the device, and then try again later.
I have attached a ZIP file containing a task list and an event viewer file reflecting what Windows thinks about my attempts to remove the device. Very recent development: The offending program appears to be ehrecvr.exe; stopping it in Task Manager allows me to remove the device safely. How do I get it to start and stop conditionally without having to find and stop it in Task Manager's process list each time?

2) When I bypass safely removing the device, my computer becomes unable to enter Sleep Mode. It will instead enter a state of fail, as I like to call it - it cannot make the final preparations for sleep mode, but it has already committed to sleep mode and cannot abort. What results is no display image, the fan continues to run, and after a few hours the screen will turn from silent black to deathly blue. The only escape is to hold down the power button and reboot. What does this ehrecvr.exe do that causes this in the absence of its spouse HP TV Tuner?

I would have posted in WMC but this seems to be a hardware issue. Device manager only shows one Avermedia tuner. These are identical PCIE cards. In device manager should it not display 2 Avermedia devices? It shows the USB vbox 3560 tuner, it shows an Avermedia tuner. Oddly WMC claims tuner...
