Any particular model of USB Hub to be used with MIDI I/O?

[GrooveEntertainment]

Is there a particular model of USB hub that should be used with PT HD?

I've got over 30 pieces of MIDI gear hooked up with 2 MIDI I/O interfaces using a USB hub but I've been having lots of trouble.

The interfaces don't 'light up' unless they are directly linked to the usb ports on the computer. But even when hooked up directly, they keep going offline or at times they just won't 'turn on'. I have the latest firmware in them but it still isn't working right.

Anyone using multiple MIDI I/O's and USB hubs? Can you share how you set it up?

Thanks,

Michael Hammar
