Query: Noisy

I don't know why but this device is noisy, it has a distinct buzz. I've tried two of these hubs and the first one was louder than a mosquito when plugged into my Powerbook, and the second is quieter, but buzzes all the time when powered up. I haven't seen how well it performs, as no matter how well it works I won't keep something on my desk which is buzzing at me.So, my advice is to look elsewhere.
