[3.5] Avoid Repeat UMD Checks?

[DragoonWraith]

I seem to remember a Feat where if you succeeded on a UMD check for a given item, you didn't have to make the check again for that item. Does anyone know what I'm talking about/where that's found? I thought it was Attune Magic Item, but that does something else.

Magic Device Attunement, from Complete Mage. Though it only works with one item at a time and you need to make a new check every day.

Thanks, appreciated.
