I was reading this thread and wondering if this could affect my decision to go for Logic 5. I have no PCI problems at all at the moment bur wouldn't like to start experiencing them if I could help it. What does anyone think?

It does depend on your MOBO.
I believe the Intel 8xx series don't have this problem since the USB does'nt pass thru the PCI bus.
And another question: how can the USB take PCI bandwitdh when it is on but barely in use?
The dongle check can't be taking that much bandwitdh,almost nothing.

hi jupiter 8
the problem is not the XSKey the problem is USB; Logic Audio up to 481 came with a serialdongle; to upgrade to 5 one has to activate USB in order to use the new usb-dongle, and this is really bad; just at the moment I´m having a serie of tests with USB and without USB; at the moment I´m recording 8 stereo-tracks at the same time in logic-audio 481, but this works only without usb
I wouldn´t go for LAP5 now (which I did); maybe emagic is coming out with a special serial-adapter for the XSKey
only a thought..

I know there is a problem with having USB on in some computers.
I wonder why?
Because it passes thru the PCI bus?
USB is like 1 MB/s! That can hardly affect the PCI bus,can it?
And why should it use the bandwitdh when there is nothing (almost) on it?
Just curious!

Yes but some (most?) USB devices are 'chatty' -- sending data every few seconds across the bus even when the device is not in use. I'm beginning to think it's not actually purely a PCI 'bandwidth' issue, but rather a PCI timing issue... (after more tests with the RD2 Geiger). And Creamware cards are definitely PCI 2.1 compliant, so...
I fixed one guy's machine which was having horrible PCI overflow problems, but having him unplug his PocketPC which was sitting in the USB docking bay.

hi,,,
maybe you are interested to know that using a USB-PCI-Card has fixed all my pci-bandwidth-problems; I put that in a thread because I think the hint is worth it.
Now I can start doing some music, .. uffff....
