I had one that looks exactly like that though it was sold under another name, and I could not decode 300baud packet at all with it. When used to play back recordings of very weak EME CW all I could hear was band noise.
I did try it on my Echolink node for a bit with no apparent problems. So my opinion is that while these cheap USB sound devices may work fine for normal computer audio they are not a good idea at all for digital modes. You may not even realize why it isn't working, or what weak signals you are missing.
