Ralph, I would check the logs in Console.app and see if there are any repetitive calls being made related to USB devices. This will usually be in the System.log if I remember correctly. If you DO see that, try disconnecting the offending USB peripheral and see if that fixes the sluggishness problem. I had a scanner once that went flaky. The symptoms were nearly as you described... sluggish behavior with no apparent reason. Looking in the logs showed connection errors for this device occurring every second, constantly.
