Sony acid Music software not recognizing my Tascam 16x08 interface

I connected my Tascam 16x08 interface with uSB cable to the same port that I have always used on my computer. Yet when I went through the sequence that I usually do (i.e. open Sony Acid Music Software, click on Options > preferences > Audio Device > Audio Device Type) everything was there but not the 16x08) How do I fix that? Or is the interface broken? Any help will be appreciated
Could also try other available USB ports on the computer. USB cables also wear out, so don't forget to try a different cable as well.
