The tech said she should be able to see the info programmed into the card even when it is taken out of the system. One card showed more info than the other card but neither was showing everything they were supposed to. After trying to activate the tech tried to look at the information on the cards and said she could not see all the info on the cards. I didn't know so I had to wait for a ground tech to come check it out. The first thing the tech asked me about was the POE filter. I had to keep calling back till they escalated my ticket so that an actual cablecard tech would call me back. Took me about 2 weeks to setup as most of Comcast tier 1 agents are clueless as how to troubleshoot. Goodluck excellent device once you get it connected. Even before activating the good cards with Comcast that setting said 'CON:Yes' The bad cards would never say yes there even when you tried to activate them. If you go to the Conditional Access menu then look at the 'CON' setting it should say Yes. That is what happened to me on every card that was bad. If you plug in your cablecard and you get OOB frequency and an OOB Lock and your signal strength and quality are at 100% but you get no Card Validation or Channel List. If you have X1 equipment with a 'point of entry' filter on your house then the box will not be able to validate. I'm sure Comcast has to support cablecards by law or something, because they sure don't like supporting them. I would think Comcast should be checking their cards, but they have no cablecard devices to check them in. Good thing too because they had no more in stock they were going to have to order one.Thank goodness that one worked. So I exchanged that one and the 7th worked. But the two new cards and the 2 hdhomeruns would not work. After 2 bad cards I bought a second hdhomerun just to be sure. The Cablecards came from a Comcast office.

The first 4 cable cards I got did not work and it was not the hdhomerun.

I'm not sure about other providers but Comcast seems bad about cablecard support.
