We've got a cube using the iSub and haven't had any problems having it plugged into a powered USB hub built in to a Sony HMD-200 17" Monitor, but I did have problems using other USB devices and this hub with system 9. This cube is running system 10.1.5 now and the built-in hub has worked since the upgrade to OS X. ck at fuzzylogical.com http://www.fuzzylogical.com
