Bummer... I ran into that very thing many years back when I needed to upgrade my OS for the business software on it. After the upgrade the sound card for my studio no longer worked. A call to the manufacturer later informed me that they were not providing the driver upgrade to the newest OS..... so there I was, without a functional studio. I was out of the home recording thing for a few years as a result. I did my homework the second time before I bought new gear.

So.....

The name brand doesn't matter.... that's up to you.

However, you do want to look for these features:

Connects via USB port
Has minimum of 2 inputs and 2 outputs (most do)
Has 1/4" and XLR inputs (high & low impedance inputs)
Uses NATIVE ASIO drivers (not codecs and asio wrappers)
Has phantom power for condenser mics
Has built in audio pre-amps on the inputs.

With those 6 features in your "must have" list, you can't go wrong.

Roland, Focusrite, Presonus, M-Audio and a bunch of others tend to meet those requirements. There are a number of interfaces that, while they work OK, are "less better" than others, so do your homework before you lay the money down or be sure there is at least a 30day no-fault return policy.

With the external USB interfaces, you have the option to move that interface to other computers as you upgrade the computer. My Focusrite Saffire ( firewire connected) has migrated from the laptop I started with to the custom built machine I use in my studio now.

You can make excuses or you can make progress but not both.

The magic you are looking for is in the work you are avoiding.
