Still working out the bugs on the new build. I *think* I have too many USB devices.
System is an Asus Maximus VII Hero, i7-4770k, 16GB memory, not overclocked, Ancient 6850 video card. Antech 650 watt supply.
Now for USB I have: Video camera, 2 external drives, printer, scanner, mouse, keyboard, two midi keyboards and the problem indication: Alva Nanoface sound card.
When I had everything plugged in (printer, scanner & midi keyboards were on an external hub), the sound would start out okay, then begin to crackle, finally get so bad you couldn't stand it. Tried plugging nanoface into just about every USB hole with the same result. The nanoface expects USB 2.0. Tried powering the hub, but that didn't help.
If I unplugged one of the midi keyboards, things were okay for most of the time. Every once in a while (days apart), I'd get the crackling again, in the same way. Tried a different hub, no joy.
I checked with the IT department at work, they said they'd had this happen once, too many USB devices, but don't know if it every got solved (it was at another division).
So I'm looking for some ideas on how to make this bullet proof. Right now the performance is acceptable, on the infrequent times when it's crackling, I only need unplug the nanoface and replug it and I'm good for a while.
Right now I have a PCI-E USB 3.0 card sitting here. It takes power directly from the system PS. I was planning on isolating the nanoface with this card. If the problem is power, this has it's own power. If it's bandwidth, then this card doesn't share bandwidth with any other USB port.
Ideals? Thanks....Steve
