I received my Novation Twitch yesterday and proceeded to plug it in after installing Serato DJ (also tried the bundled ITCH 1.8 and the updated 2.2.2). At first the controller didn't register with windows, prompting a hardware failed to install fault. I downloaded the drivers from Serato/Novation and installed and Windows seemed to register the hardware. When entering Serato DJ/ITCH, the software would intermittently recognise the hardware. I proceeded to try a variety of cables and ports on my computer, all giving the same results, as well as loading the software before and after plugging in. The hardware seems to have a variety of lights on it flashing on/off rapidly and the software, when recognising the twitch, proceeds to do what it feels like. When I was able to load a deck, the song automatically started over and over from the start (as if i was mashing the play button). Failed to get any further so looking for suggestions. Is it a hardware fault? Shall I return it?

PS. When loading ITCH/DJ, the hardware prompts for a firmware update that fails every time with ERROR #: -1
