To resolve USB detection
difficulties, please follow the procedures below:
If the unit has a "reset" button,
you can try to reset the unit first before connecting it to a USB port.
If you are using Windows Vista, please download and install the Cumulative
update rollup for USB core components in Windows Vista, available at http://support.microsoft.com/kb/941600/.
Download and install the latest Service Packs for Your Operating System,
and BIOS/Chipset Update for your system
If you receive any errors about usbstor.sys, be sure to download and
install the latest Service Pack for Windows 2000 or Windows XP. If the same
USB product is working properly in a different system, it is recommended that
you check with your system vendor for a possible BIOS or chipset update.
Ensure the USB cable is no longer than 5 meters in length
The maximum cable length allowed by USB is 5 meters. It is possible to extend
the connection by joining 5 meter cables with powered hubs, or using USB
repeater cables. For troubleshooting purposes, we recommend that the cable
be no longer than 5 meters.
Connect the device directly to the USB port built to your motherboard
Although a single USB Port is capable of branching out to 127 devices, some
devices require a direct connection to the USB port on your PC or Laptop.
If your device is currently connected to a USB port in front of your PC ,
try to connect it to the USB port at the back of your PC.
If the difficulty persists, try the device on all available USB ports. Some
devices can react differently on different ports. Therefore if you are experiencing
problems, try swapping the device to another USB port ( if available).
Ensure that you have installed all available updates for your USB drivers
and for your motherboard (e.g. Bus Mastering or IRQ Routing drivers)
Drivers and software can become outdated quite quickly. New drivers and software
are posted frequently after a product is released. To find a possible update,
check with the system manufacturer. Should this prove unsuccessful, check
with the motherboard manufacturer. As a last resort, check with the chipset
manufacturer. It is advisable to verify with system vendors to ensure that
generic drivers work with your system configuration.
If you are using Windows XP/XP Service Pack 1, we recommend downloading and
installing the Microsoft USB update available at http://www.microsoft.com/downloads.
Please note that users of Windows XP Service Pack 2 do not require this update.
Use a self-powered USB hub
If, after connecting a USB device to the system, the system crashes, locks
up, or elicits other abnormal behavior, you are likely to be putting a strain
on your power supply.
One way to resolve the power issue, is to use a self-powered USB hub. By using
the self-powered hub it eliminates the strenuous drain on your systems' power
supply, because all power going to devices connected to the hub, comes from
the hub. Please be aware that some USB devices may need to be connected directly
to the internal USB port, in which case, please make sure that the internal
USB port is powered.
IRQ conflicts can cause a number of problems with USB connections.
First determine if you are using onboard USB ports, or a USB interface card.
In either case, please refer to your hardware manufacturers handbook, website,
or support service for specific information regarding your controller. For
more information about IRQ conflicts, please click on IRQ - General Information and Essential Troubleshooting.
If you find that the USB microphone no longer appears in Multimedia properties
after installing the Sound Blaster Live! experience software in Windows 98,
we recommend that you try the following:
Go to Start, Programs, and click on Windows Explorer. Browse to C:\WINDOWS\SYSTEM\VMM32.
Locate and highlight the file VMCPD.VXD, then right-mouse click on it, and
choose Rename. Rename the file VMCPD.VXD to VMCPD.OLD. Restart Windows 98.
The original release of Windows XP does not support Enhanced Host
Controller Interface-compliant USB host controllers (USB 2.0 ports).
This causes a minor compatibility issue when using a USB 1.1 devices on a
USB 2.0 port in Windows XP.
If you find that installing drivers for Creative USB cameras in Windows
XP system with USB 2.0 ports, causes your system to restart automatically, or
results in a blue screen, it is recommended that you download and install
Windows XP Service Pack 3 from Microsoft.
Windows detects the SoundBlaster USB MP3+ but does not properly enumerate
the device. By default Windows XP will install the native USB audio drivers
if the USB device is not correctly identified when attached. This is generally
the case on laptops where the enumeration cycle does not properly allocate
full power to the USB device in the time Windows XP allows for power up, therefore
Windows can not correctly identify the SoundBlaster USB MP3+.
- Boot the system with the Sound Blaster MP3+ USB attached.
- Reinstall the software & drivers then reboot.
- Open the Device Manager.
- If Windows XP identifies the Sound Blaster USB MP3+ as a USB Audio device,
right click on the listing and select Reinstall Driver.
- In the driver wizard which appears, select the Sound Blaster USB
MP3+ and select OK.
- The correct driver should load at that point. The Creative software
application should now be able to detect the Sound Blaster MP3+.
When a Creative USB Webcam and Sound Blaster Extigy are connected to the
same USB controller, the system may reboot. If this happens in your PC ,
please try one of the following options:
-
Connect the Sound Blaster Extigy before connecting the webcam
-
Connect Sound Blaster Extigy and webcam to different USB controllers
if possible. Some older computers may have one USB controller only.
-
Stop Live Video of your webcam if 5.1 audio output is needed.
