Conectiv

Issue: Power Spikes/Fluctuations can cause the device to go offline and stop communicating with the computer. Audio input and output will stop functioning.

Workaround: There is no definitive workaround. Recommendations include using a power conditioner/surge protector; using a USB cable w/ ferrite bead; keeping all power supplies, neon & fluorescent lights, and other EMI emitting devices away from Conectiv; and connecting other DJ and lighting equipment to a separate circuit when possible.

Q: I used up all of my computers built-in USB ports. Can I use a USB hub to connect my M-Audio device to my computer?

A: Do not use a USB hub during the driver installation! Install the drivers with M-Audio USB device connected directly to your Computer’s USB ports without using a hub. Once the drivers are installed and verified that your M-Audio interface works as expected that way, you can test the device with a USB hub to see if it still works properly. Most USB hubs we've tested worked fine with MIDISport Series products and USB MIDI Keyboard controllers. When using a USB audio device on a USB hub, keep in mind that all devices that are connected to the same hub have to share the native USB port's bandwidth. This means that it is more likely to run into problems when the bandwidth limit of the USB port is reached.

If you experience any problems, you should use the device without the USB hub. If you are thinking about purchasing a new USB hub, we recommend using a powered USB 2.0 hub that uses it’s own power supply. We've had very good experiences with powered USB hubs by “Griffin Technologies” and “Dr. Bott”.

Q: My M-Audio USB Audio- or MIDI interface fails to install, doesn't work after installation, or drops out of the system every now and then. What could be the cause of this?

A: A common reason for such problems is the Power Management function of the USB Root Hub. Under Windows XP, disabling the Power Management for all USB Root Hubs in your system should resolve this problem:

1. Open the Device Manager (Start-> right click on "My Computer", click on "Properties" -> Hardware -> Device Manager)
2. Look under the category Universal Serial Bus controllers and find the USB Root Hub.
3. Right click and select Properties, go to the Power Management tab
4. Uncheck the box "Allow the computer to turn off this device to save power." and click "OK".


Repeat this for each of the USB Root Hubs shown in the Device Manager.

Performance issues with multi-core processors (Windows XP)
Text size [-] [+]

Computers that are running Windows XP Service Pack 2 and that are equipped with multiple processors that support processor power management features may experience decreased performance.

Symptoms
Computers that are equipped with multiple processors that support processor power management features, such as Advanced Configuration and Power Interface (ACPI) processor performance states, require Microsoft Windows XP Service Pack 2 (SP2). Additional updates are available to optimize performance and behavior on computers that are running Windows XP SP2. Without these updates, computers that are equipped with these power management-capable, mobile, dual-core processors may experience decreased performance or unexpected behavior.

Resolution
For users experiencing any of these symptoms, including irregular playback of the Click-Track in Pro Tools, the following file is available for download from the Microsoft Download Center:

Download the WindowsXP-KB896256-v4-x86-ENU.exe package now

Note: It is always a good idea to back up your valuable files before making any changes to your system.


MORE INFORMATION
Windows XP SP2 is required on computers that have multiple CPUs that support ACPI processor performance states. This requirement includes computers that support the following items:

• Multiple physical sockets
• Multiple-core designs
• Multiple logical threads, such as Intel hyper-threading technology
