I just bought a used Tascam US-16x08 interface. I downloaded the software the goes along with it and it wont recognize the interface when its plugged in through the USB. The download said it included the drivers but it seems like it was the only the 16x08 software. I also downloaded the firmware it told me to download but when I run that it says " The supported device is not connected" So this has me thinking my entire computer just wont recognize the interface at all. Did I just buy a broken interface? It said it was working and in good condition. I'm using windows and use pro tools. Someone help.
