Troubleshoot if the Sprint SmartView software does not detect your U301 USB Device Sprint 3G/4G Mobile Broadband

Last Updated: Nov 04, 2015

Please be sure that you install the Sprint SmartView software from the CD in the box before inserting the U301 in your computer.

If you've installed the Sprint SmartView software onto your desktop and your computer is not detecting the U301, here are several reasons why this behavior may occur:

  • If the device is plugged in at boot up, sometimes the device is not recognized. You will need to:
    1. Validate that you are on version SSV 2.28 that comes on the CD or above
    2. Pull device from computer
    3. Close Sprint SmarView and re-open
    4. Re-insert the device
  • The U301 is not fully inserted into the USB port on your computer. The U301 must be fully inserted into the USB port of your computer either directly or using the provided extension cable in order for the drivers to be installed and the SmartView software to recognize it. To verify this:
    1. Remove and reinsert the U301 into the USB port on the computer
    2. If this does not resolve the problem, try using another USB port (if available)
    3. If the USB Device is still not recognized, remove it and reboot the computer; once the computer is booted up, plug in the USB Device again
    4. Ensure the U301 is plugged directly into a computer, not a USB hub
  • If you are using the supplied USB extension cable. Please make sure you have inserted the connector end into a USB port and properly connected the USB cable to your device. Use only the supplied USB extension cable; other cables may not work with the U301.
  • Whenever the U301 requires a reset, occasionally the SmartView software will close unexpectedly. Device reset reasons include plugging or un-plugging the device, applying PRL update or updating data profile. To correct this:
    1. Remove the U301 from your computer
    2. Re-insert the device
    3. Re-open Sprint SmartView
  • Another application is conflicting with the U301 SmartView software. Ensure that applications such as ActiveSync, HotSync, WinFax and/or other connection managers are not running in the System Tray (the icons located by the clock on the Windows taskbar) while using the SmartView software.

If the steps above do not resolve the issue, please contact Sprint Customer Service for assistance.
