low speed hi-speed USB) between host and devices, so it can really influence particular compatibility. That priority change is only possible for another downstream devices, which are connected to the same hub, otherwise it can't influence communication with other devices connected to different computer ports.īut as I've mentioned, hub has its own buffers and translates communication (incl. I am thinking this priority protocol would be a good thing with the audio data. Without the hub the data gets corrupted and the file stream fails. says when a hub is plugged in the computer gives it priority over all other USB devices. I have a CNC machine that comes with a USB hub, because the mfr. Reliability over some reasonable timespan is always matter of particular device, it's construction, thermal design and associated strain at components etc. Of course, when you use the interface just sometimes, it might be different situation.
Of course besides some servers, network infrastructure, control units etc. I've always used power distributor or central room switch, when I finish work and leave the place. I don't put that into relation to operating hours really, cause I don't want to limit myself by thinking about that and of course, when I turn that computer on, I likely use all sound devices vendors often put in into to smallest possible case, use cheap caps specced for lower temperature etc. maybe besides some cheap worldwide certified power supplies, but that's nature of that. I have couple of pretty old audio devices, which I almost never turn off when working with computer. That's a difference of 41,200 hours of unnecessary use. If I use it 10 hrs a week that's 520 hrs per year and only 2,600 over 5 years. Electronic devices have a finite life, so if left on for 1 year is 8,760 hrs. I only use the Babyface now and then so leaving it on 24/7 seems like unnecessary wear and tear on it. switch operates only at 5V DC power line. It's often used for USB bus powered single board computers. Then check electric installation at the place and get an UPS to protect not only your interface, but also computer with data itself, it's much better investment in long term.Īnyway, if you really would like some USB power switch, then get this short extension cable by Adafruit You might have different concerns, like if you live in area, where you're often experiencing some voltage fluctuations or power surges etc. the same component might fail 20min after first unboxing.
It's not possible to say, it would be different, when you'd use it less time by turning it off regularly. If your previous interface (assuming powered one) catch on fire, there was probably some internal faulty component causing a short and raise of internal temperature. I've used many interfaces over the years and haven't found any detrimental effect of leaving it on, when I'm working with computer and turn everything off by central switch, when I leave the room. That's why is typically recommended to use USB audio interfaces directly at own host port at computer.Īlso I don't see any point of "saving" interface by leaving it off. Problems with that aren't typically related to latency, but rather to some possible intermittent issues with devices detection via cascaded hubs, power saving and bandwidth allocation in case of multiple downstream devices. You likely won't have any particular issues with hub and one peripheral device, but generally it's absolutely unnecessary interception to USB communication with root hub, you have in your computer. some compact notebooks) or some tablet without sufficient power for external peripherals (although this isn't really problem for BF Pro, as it has external PS input). I won't recommend to use any hubs with audio interface, unless it would be really necessary for a computer with lack of ports (eg.
