The hdpvr killer is a hardware usb device made by Gavin Hurlbut. Its
essentially a relay connected to a usb port which allows you to
physically kill the power to the hdpvr.
I'm personally using a four relay phidget
(http://www.phidgets.com/products.php?category=9&product_id=1014_2) that
I already had lying around, though in truth I haven't had to actually
use it in several months now, my old backend was rock solid...
unfortunately it died after 5 1/2 years and had to replace it last
week. Which is where all my USB 3.0 issues started. It's worth noting
that the xhci_hcd module is still under fairly heavy development, so I'm
hoping Sarah Sharp will tame it yet.
If you're having the same issues I had, the hdpvr will work once, fail
twice, and generally work again, fail twice, etc.
Good luck,
Andrew.
