when you download off the site there are two setup files. What I did was installed both of them and it worked.
the only problem Im having now is having no "monitor" output during recording, but im trying to figure it out on my own as of the moment hehehe
i had the same problem..just go to option menu then monitoring, then choose either always input or smart input..im not sure what the diference is, but there seems to be none..then there!just arm a track for recording and monitor away! =D
btw, in the latence settings of the uca, if you have enough resources on your computer, theres an option on the driver settings that lets you lessen the latency, im not sure what was the lowest value but it was way below 17ms..
also, downloading and installing the driver from the behringer website is a must..improves the performace of the uca by a whole bunch..and just fixes the little problems anyone may be having
