I have disconnected everything from the back of my iMac apart from the Virus Ti (even disconnected USB keyboard). I then everything up, put the Virus plugin on a channel in logic and now get the following error message...
"A device called 'BRCM2046 Hub' sharing the same USB root hub with the Virus Ti has been detected. This is a potential problem ad might cause sync errors and audible artefacts when using Total Integration. Try to solve this problem by using another USB port instead.
(Root hubs are usually inside your computer and therefore cannot be recognised easily as hubs. Trying out other USB ports for the Virus TI might solve the problem. By changing the USB layout and hitting the Rescan button you can evaluate if the problem persists."
I have tried all 4 ports on the back of my iMac.
Here is some more info on my setup if its any help.
iMac 2009 i5 2.6Ghz
12GB Ram
Virus TI software & firmware is the latest stable version (4.5.3? cant remember the exact number)
After a quick google I read the the BRCM2046 Hub is something to do with the bluetooth. The only bluetooth device I am using the an Apple Magic Mouse, my keyboard is the USB version.
So yes I would say this is definitely some sort of USB problem, or audio sync issue. Any ideas?
Thanks again
