How do I get to the hardware vendor site?
You don't. Vendors don't supply drivers
. If you can find out who made the device, the manufacturer sometimes
has drivers. Newegg.com - AFT XM5U All-in-one USB 2.0 Card Reader
I have this one. It works right out of the box with no additional drivers on Windows 7. It also has a Micro-SD slot so you don't need adapters. About the only complaint I have is the power light. It's bright so I put a tiny strip of black electrical tape covering all but the upper ~1/5 of lens. The power light on my case was the same way so it got the same treatment. That thing was like a LASER.
I'm not into the light thing with PCs but they may not bother other folks. Besides, my Antec Veris puts out enough light for the whole room.
