My usb device i/o error

Two of the most common causes of I/O (Input/Output) device errors are driver based. Typically, either the device's driver is not enabled or it is out of date. The driver component has an important function, as it acts as a motorlike force that propels USB/plug-and-play hardware into a driving action within the computer. It is the connecting communicating link signaling the CPU to a desired movement. And while not all I/O device error solutions are simplistic, as a good starting point, you can try troubleshooting using a few basic steps, and you might not need to attempt anything else. Access "Control Panel" from the Start menu and then choose "Performance and Maintenance." Click "System" and then go to the Hardware tab and click on "Device Manager." Find the device that is registering an error by expanding the nodes of the appropriate category. If the device has a red "X" on the icon next to its description, the hardware is disabled; proceed to Step 4 to enable it. Otherwise, go to Step 5. Go to the General tab and click "Enable Device" found under the Device Status section; then press "OK." (Note: You may have to follow prompts, as indicated through an enabling device wizard. If you do, continue to click "Next" and follow the prompts until the process has completed.) Test the hardware. If an error is shown, proceed to Step 5. Go to the General tab and click "Troubleshoot" found under the Device Status section then press "OK." Follow the prompts to solve the issue. If an error is still shown, proceed to Step 6. Go to the Driver tab and click "Update Driver." Follow the prompts until the process has completed and then test the hardware.

Click "Start" button, type "devmgmt.msc" (without quotation marks) in the "Search" bar and press "Enter". Click "Continue" if necessary.

In Device Manager, double click to expand "Universal Serial Bus controllers", right click on the Host Controller, click "Uninstall" and click "OK".
