No matter what I do, I can't get it to work... snap crackle pop at any latency setting.

Firmware latest. MPC software latest. Plugged into USB 2 port. All plug-in's disabled. Onboard sound disabled in bios.

Hardware works fine on Mountain Lion.

New powerful Dell Machine w. i7 processor.

What gives?

Did you deactivate USB 3 protocol in BIOS, too? I read that was a common problem.

No soundcard, just the MPC only. I even disabled the onboard sound in the Bios

The bios in my dell enables me to disable USB ports by location, (front, top, rear, etc), so I disabled them and left only the top (USB 2) on. I'm not sure if that actually disables USB 3 or not though.

At any rate, it will work for a few minutes, then, it will start crackling and popping. If I restart the hardware, it will no longer respond. Or, sometimes, it will develop about a one second latency after a few minutes of working on it, meaning, if you push play, it will take almost a second before the sequence starts playing, ditto if you push a pad.

Everything works fine on the Mac. What's going on here?

I had the same some time ago on my mac with a Tascam Interface. First all is ok, after a while i got latency on whatever i do, which got longer until it startet crackling. I had to restart the interface and the OS to get it all going again.
Was no Problem with the OS itself or the Software, there was a problem with the Interface Driver...(in my case)

Edit: MPC Software works on my (cheapest of the cheapest) Win8 Tablet....i cant really use Plugins because of the low ressources, but no really latency and no crackling on it when i just play around with the mpc

the driver you want to turn up shows up on my system as 'intel usb 3.0 controller' or something like that.. which physical port doesn't matter, once the usb 3 driver is turned off you can use a 3.0 port and it will function as 2.0.

good luck as not all systems allow you to access the driver in question. i imagine this problem is only going to become more and more common as people upgrade their computers. if you have one 3.0 port it doesnt matter if you use a 2.0 port or whatever, you are going to have this problem. hopefully a driver update will roll through, but i am extremely skeptical as the company responsible for the rens interface design and audio driver seems to be a 3 man operation running on a shoestring budget : http://ploytec.com/

actually when i just googled ploytec the description on google said "usb 3.0 audio and more!". i don't know whether that is some kind of sick joke or an indication that maybe there will be a driver update :?

fdodds I did find that driver, but when I disabled it (in device manager) it says you have to restart the machine for the change to take effect, and when I do that, the driver is back again.

Kind of sucks that I spent a bunch of money to have all these USB3 ports, and I can't use them if I want to use the REN.

In fact, I've given up hope and have gone back to Mountain Lion, where it works fine.
