Hauppauge WinTV-NOVA-T-500

This is a Hauppauge Dual-tuner PCI card. It's actually a USB device, with the USB controller and USB dual-tuner on a single PCI card. There aren't any real USB plugs or sockets involved.

I've got 2 of these, which are different revisions of the board. This one is rock solid:

$ lspci
00:13.0 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 61)
00:13.1 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 61)
00:13.2 USB Controller: VIA Technologies, Inc. USB 2.0 (rev 63)

This one has the random USB disconnects problem:

$ lspci
00:13.0 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 62)
00:13.1 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 62)
00:13.2 USB Controller: VIA Technologies, Inc. USB 2.0 (rev 65)

Note that chip is a different revision number.
