USB hub conflict with ProTools???

[bross]

Since my Mac has only 2 USB ports and I need more than that, I added a USB hub. Now I get one of two general OS error messages when lanching ProTools:

-error type 2.
-error type 3.

Basically, I can't even open ProTools now when I have the hub plugged in.

The hub is made by Griffin Technology. I've also tried other hubs and come up with the same errors.

My setup:

Mac G4--533Mhz
MacOS 9.1
768MB RAM
ATIRadeon 8500
ProTools 5.1 (with 1 Mix Card and 1 Farm Card)

Anyone have any suggestions on how to fix this (other than having to unplug the USB hub everytime I go into ProTools)?

Bross,

Is the hub powered? Also, what devices do you have connected to the hub? If your running an iLok on the hub, you may want to try moving it to another port. Type 2 and type 3 errors are usually caused by a RAM issue or corrupt software.

Thanks for the reply. I got it working yesterday by upgrading from PT 5.1 to PT 5.1.1.
