> Mbox/usb Issue With Passive Hub, won´t work after using passive hub

I plugged my Mbox into a passive USB hub which at the same time had another passive hub plugged into it (the Mac extended keyboard with mouse). The Mbox worked but had ferocious noise. I now know this was a mistake and the MBOX won´t work with a passive hub.

The problem is that now the Mbox won´t work through the actual Mac USB ports. With PT LE 5.2, I get an error saying "cpu usage is holding off usb audio, increase h/w
buffer or remove plug-ins". With Digital Performer 3.11 it just crashes the program after about a minute, and sometimes even freezes the Mac. None of this ever happened before.

Another symptom: I boot the Mac with the Mbox plugged in, but don´t open any audio programs. I unplug the Mbox, plug in my DSL modem, and the modem won´t boot up. Once I reboot the Mac, it works fine.

So the Mbox is obviously doing something funky to the USB port, or vice-versa.

I´ve reinstalled USB driver for Mbox, re-updated Mbox firmware, reinstalled Digi extensions, all to no avail.

Anyone got any ideas?

Thanks!

...Sounds bad, I hope it's still under warranty.

Have you tried to reinstall your OS? (Sometimes you just have to start over.)

Also, try to set it up under your 10.2.6 partition. If it still exhibits issues, you can then be fairly sure there is a prob with the mBox.
