Yellowtec PUC2 Mic LEA

I have a audio interface it's called tascam us-200 before. It's stable but the quality is not good. I like singing so I need a better interface. yellowtec puc2 mic is very suitable for me. Although it doesn't have enough inputs and outputs, just for recored sound it's enough.I have a problem that only when I use the record software I can open the asio driver and choose the 24bit to record, otherwise it's showing that is WDM and the highest record is 16bit 192khz. I don't why. But it doesn't matter when i use it.
