USB devices dropping, stuttering, etc
RandyT:
If all of this is on the same physical port, and you are powering LED's from the USB port, which are active in the attract mode for the FE, then there's very likely too much power being pulled from USB port. This can certainly cause the issues you are seeing.
The remedy is to distribute the devices between multiple physical ports (keeping in mind that each physical port can have two or more connectors), use a powered hub, and/or power your LEDs directly from a power supply instead of the USB power.

well technically they are all physically plugged into separate ports but maybe I'm misunderstanding? There are a total of I think 8 USB ports on the CPU. You may have a point though on the power draw. I have a separate 5V from a power supply going to a terminal block powering all the LED's but whatever power the LEDWiz needs is coming from the USB connection. A powered hub might be the way to go. I suppose if that's the case I could also test the theory by unplugging some of the devices?

That should take the LEDs out of the equation, but the total of the USB devices could be more than the port can supply. Unplugging a couple of devices would be a very good way to determine if that is the issue.
