[LAU] high latency with usb controller during high cpu loads

Hello list,
Is it possible to prioritize irq of a usb device? I have the behringer bcr2000
midi controller, plugged to a usb port, and i experience really heavy
latencies when cpu is on a high load (latency > 1s). During normal system
operation it's ok, latency is practically realtime.

thanks.
