Google the "DPC Latency Checker" and use that tool to analyze your system performance. CPU utilization isn't a reliable indicator for DAW performance. Most likely you have a misbehaving driver on your system that is killing your latency and overrunning your available buffer setting. My Windows 7 box is now running at about 20 microseconds (as reported by the DPC latency checker) and is running flawlessly. I had to be very, very careful when setting it up though. I watched the impact of every single driver install individually to see it's impact on the machine. Interestingly many 3rd party drivers caused problems. Drivers updated through Windows Update did not. Especially watch out for "bad" video drivers and WLAN stuff. Disable every piece of hardware you don't really need (parallel ports, serial ports, etc.) and disable system device drivers you don't need (Google "Black Viper" Windows optimization info).

I tried the DPC Latency Checker.
Test Interval : 976
Current Latency: Unstable, Average around 600
Absolute Maximum: 1071
This Machine should ba able to handle real-Time streaming of audio and/or video data without drop-outs.
For some odd reason, I get the dropouts early when the toneport is just started, i always leave it plugged in, as i have an external drive, and a wireless mouse receiver plugged in through my three usb ports and only three. I don't get why it has to "warm up" When I use to just start it and be ready to go. I will try my toneport on another computer, the only issue with that computer is that it doesn't recognize the internal video gpu driver. But i will, try it to see if it is faulty hardware or the drivers in my laptop. Right now, I am using the toneport, i have it set as the WMP sound device, It is playing quite well, but then it starts to pop. I don't strain my computer at all, only when playing a video game, even then I use to run high end games and the toneport would perform flawlessly. I can still do that though, but it consists of the pops, clicks, and ms dropouts as I currently am using WMP.
When the Toneport is not in use:
Test Interval : 976
Current Latency: Unstable, Average around 50
Absolute Maximum: 390

Another issue to watch out for is that with USB devices you need to be careful about what devices are sharing a USB Host Controller. You can see what's happening with your USB controllers by going into Device Manager and checking the properties of each of the USB Host Controllers. Within the properties window is an "Advanced" tab that will show you which devices are connected to that particular controller. You do not want your mouse, keyboard, etc. sharing the same controller as your TonePort. You should move an obvious device around (like your mouse) connecting it to each of your available USB ports to see which controller each of the ports use. On a notebook machine you're very limited in what you can do to connect the TonePort to its own controller. This is why I have my notebook (my poor man's DAW) setup on a docking station that has a PCI USB/Firewire card installed. I connect my audio devices to the card and not to the integrated shared USB ports on my notebook PC that serve my other peripherals.
