Hello, all! I am a recent purchaser of the Buffalo Tech's USB 3.0 Interface Card (IFC-PCIE2U3), and so far it works well. It installed without problems, reads devices well, and works with my other devices (especially a USB 2.0 gaming keyboard) well. Except for one minor problem...
When the computer enters sleep mode or shuts down, the card (or, specifically, the Renesas Electronics USB 2.0 MTT Hub that it adds to allow backwards compatibility with my USB 2.0 devices) doesn't reactivate itself when the computer boots back up. Thus, all USB 2.0 devices attached to the card, like the aforementioned keyboard, do not operate, and the only way to fix this problem is to completely reinstall the card's drivers from the website. (Which only lasts until the next sleep mode or shutdown, of course.)
Constant Google searches and fix attempts have been fruitless so far. The keyboard has features that only work effectively on USB 2.0+ ports (of which my computer has only this card), and so I sought to use this card to both grant the keyboard the improved connection it desires, as well as be able to use other USB 3.0 devices. However, if I have to reinstall the drivers every time I boot the computer up (something that could happen in the range of four+ times a day; I do not like to keep the computer on unnecessarily.), that would be enough of a breaking point for me to return the card and acquire a 2.0 card in its stead. Before I do that, though, I wanted to check if there was some sort of fix to this problem that I couldn't otherwise find.
