I bought Behringer audio device (FCA610) and I would like it to only be turned on whether the computer is turned on as well.
There are two ways to power on the device: either via FireWire or an external adapter. My FireWire port would only power the device while computer is turned on, but I had problems making my Ubuntu also use it for transferring audio.
Because of that, I connected my sound card to both FireWire and USB and have concerns about whether there is any chance I could end up damaging the device in the long run. How likely is it that connecting it via both input modes is something the designers hadn't thought of and the device would break over time? (I already tested that this setup doesn't break immediately).
