Can you have two Overhubs on one computer

Hi,

I have a large setup with many USB devices. I also own one overhub which seems to work just fine. I do have two other hubs of which one seems to have a lot of troubles keeping midi enabled devices connected. I keep loosing connections all the time. I replaced it with another hub, but I keep getting the same results. Does anyone know If i can replace this one with a second overhub. I guess it should work, but last time I had huge issues when connecting two exactly the same hubs to my system. It threw my entire midi system out of wack. It was so bad even my mouse started doing strange things. I don’t mind the price, I just want a stable setup. Oh, I’m on the latest OSX btw.

Thanks, Ronald.
