USB devices cannot be recognized.

# You plugged a USB device (such as a printer), however, it cannot be recognized without unplugging and plugging it again. # To make the USB device recognized, you unplug and plug it every time you use it. Is there any way to avoid such operations?

On the Resources tab of a USB device's Properties, clear the "Use automatic settings" check box, set the I/O address to the default value, and then confirm that there is no conflicts. # Notice: If you add the peripheral that uses the I/O address, recognize such peripheral first, and then make the above setting. 1. In System Properties, click the Device Manager tab. 2. Click [Universal Serial Bus controllers] and then double-click [Intel 82371AB/EB PCI to USB Universal Host Controller]. 3. Click the Resources tab, and clear the "Use automatic settings" check box. 4. Select [Input/Output Range], and then click the Change Setting button. On the [Edit Input/Output Range] screen, set Value to the default value. Make sure that there is no conflict at that time. 5. Click [OK] twice, and then you receive the message, "Creating a Forced Configuration". Click [Yes]. The USB resource is fixed.
