Troubleshooting Common Problems with Your Powered USB Hub

Although a powered USB hub is of the most current technology and is often durable and easily configured, the system can still malfunction. The following article mentions some of the common problems people encounter when using USB hubs. It also also gives a run down on some troubleshooting measures. The scenarios and troubleshooting measures discussed in the subsequent sections generally apply for Windows XP but can be used to diagnose and repair problems on other operating systems.

USB Trouble after Upgrading Windows XP

One of the most common problems that people encounter in powered USB hubs is a system failure once the operating system has been updated. In most cases, the problem starts once a computer has been upgraded to Windows XP. Usually, when this happens, it’s best to check first if the software matches with the USB device. In order to determine the compatibility of the two, go to Windows XP hardware compatibility list (HCL). This is available through Window’s website. Check the compatibility of XP to the USB hub brand you own. If it is not compatible, there are downloadable drivers available. These drivers should be installed for the USB device to work properly.

Note: There are instances wherein there are no specific drivers listed under a particular type of USB hub. The only probable solution for such is to initiate a trial and error for each driver. See what driver will help make the USB hub functional again.

USB Devices Are not Recognized

If a USB device is not recognized no matter what port it is plugged into, then there is a problem with the Windows or BIOS configuration of the computer. There are instances wherein BIOS in some computers offer a configuration option. This option allows the user if IRQ will be allotted for the USB device. Although in some computers the option may appear in a different prose, the bottom line is to click on Yes or On. This option depends on the version of the BIOS and its manufacturer. If this configuration is not done, no USB device or hub will function.

Another problem why USB devices may not be recognized is a glitch in the USB Controller configuration of the computer’s Windows XP. In order to see whether the USB controllers are functional, go to Device Manager and try to increase the default setting for the Universal Serial Bus Controllers node. Under this option, there is the USB Root Hub or the USB Universal Host Controller selection. There should the different specifications that match a certain USB hub. It is important to change the disabled ports for the device to function. Disabled ports are marked with an X over them. Change this part by selecting Enable.

In order to make sure that the right drivers are used, check it using the Device Manager. Under the Device Manager right click the USB component option and then go to properties. Select the Driver tab. Refer to the manufacturer’s site for compatible driver information.
