I use a Yamaha Audiogram 6 USB Soundcard with my PG Software. It has a nice little mixer for connecting up with. It also has onboard phantom power as well. They also have ASIO drivers on the Yamaha site. Check to see which OS they have updated. I have Vista here and they had the 32 bit ASIO driver for my set up.

Connects via USB cable. Works very well with my keyboard and Biab at the same time, no latency problems etc . . .
