Click on the Hauppauge device to open it. If you see the following: "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)" 

 This appears to be a bug in Windows 64 bit OS since the Hauppauge Windows drivers are signed.

Under 11.1 Works a perfectly with MythTV. Can't recall if needed to install ivtv or not. But it works fine. Unable to test digital tv input - poor reception. Hardware encoding, means low CPU use. (MythTV defaulted to software encoding, but simply selecting the IVTV mode - using hardware encoding - works). Update: Works DVB-T and Analogue. One problem is cannot switch from Analogue to DVB-T in 11.1. Latest drivers from linuxtv.org fix this.
