I have used the Digimaster USB Minipro interface that was recommended to me by a friend, I am very impressed.
I have used the interface with a Yaesu FT817ND and an Icom IC7400 using PSK, SSTV and EasyPal on both radios with no trouble whatsoever.
The USB MiniPro is a small interface that takes up barely any room on my desk in my shack.
