Why Does My USB Device Freeze When Plugged into the Front USB Ports on My Desktop PC?

Hardware: Multifunction DAQ (MIO)>>Portable

A USB device is either freezing when plugged in or is not recognized by the computer at all when plugged into the front USB ports. How do I fix this?

There are multiple ways to address this issue:
  1. Use a USB port on the back of the desktop PC.

    USB ports on the front of desktop computers are designed for convenience when plugging in small devices such as a flash drive or a small camera. Typically, front USB ports are not designed for use with higher bandwidth devices such as external hard drives, MP3 players, and data acquisition devices.The back plane has both higher power output and bandwidth that is required to power most devices. Use the back USB ports to ensure the device has adequate power. To circumvent the lack of convenience, a USB extension cable may be used to provide a convenient port to the back of the computer. If the problem lies with the power distribution, adding a powered USB hub may resolve the issue.

  2. Update the device drivers.

    Another thing to consider is making sure that the device driver is the most up to date. You can find a complete list of drivers on the Drivers Page. After downloading the driver that matches the USB device, make sure to restart your computer.
