Locating updated drivers is easy!
Because USB devices are Plug and Play devices, there is little that you can do to control or configure them. However, you can trace most USB problems to one of the following conditions:
- Malfunctioning or incorrectly-configured hardware
- Malfunctioning, incorrectly-configured, or missing device driver
- Mismatched cabling
- Out-of-date firmware or basic input/output system (BIOS)
- Incorrectly-configured root hub

Malfunctioning or incorrectly-configured hardware
Typically, if you plug a malfunctioning or incorrectly-configured device into a USB port, it causes the computer to stop responding (hang). In most of these instances, you must physically turn off the computer and turn it back on to reset the bus. Be aware that it may be more difficult to identify which device is malfunctioning or is configured incorrectly. If another computer that you know is working correctly is available, try to plug the device into that computer to see whether you encounter the same issue.
If the device is plugged into a secondary hub, unplug the device from the hub, and then plug the device directly into the root hub.
Many hardware problems (such as high or low power, bandwidth shortage, malfunctioning or incorrectly-configured firmware, and so on) can cause issues to occur.
Check Device Manager to be certain that the root hub is functioning correctly. If the root hub is displayed with an exclamation point (!) in a yellow circle, verify that the BIOS is assigning an interrupt request (IRQ) to the root USB controller. This is required for the device driver to be loaded. For more information about how to use Device Manager to troubleshoot hardware issues, click the following article number to view the article in the Microsoft Knowledge Base: 133240 (http://support.microsoft.com/kb/133240/ ) Troubleshooting device conflicts with Device Manager If no devices work when you plug the devices into the root hub, verify that the power requirements of the bus are not being exceeded. USB devices can draw a maximum of 500 milliamps for each connection. If a device tries to draw more power than this, the specification recommends that the computer should be able to disable that specific port until the computer power is cycled (this is known as "suspending" the port). In addition, if the device draws less than 50 milliamps, the port never becomes active.
Check the Power tab in USB Root Hub properties to check the power usage of the USB bus.
Malfunctioning, incorrectly-configured, or missing device driver
When you plug in a USB device, the computer should load and then configure the device without ever requesting a device driver (assuming that the device falls within the defined and supplied class drivers). If the computer prompts you for a device driver, check with the manufacturer of the device to determine whether a driver is available.
Mismatched cablingThere are two types of USB cables, high speed and low speed. Low-speed cables differ from high-speed cables primarily in their shielding. If you plug a high-speed device into a low-speed cable, you can cause signal distortion over long distances.
Verify the USB chain is working correctly to be certain that a device that requires the ability to draw power from the hub is not plugged into the chain on the other side of a non-powered hub. This causes that hub and all devices down the chain to be suspended. If the hub is a powered hub, verify that the power supply for that hub is configured correctly.
Out-of-date firmware or BIOS
The key to all USB devices is the firmware. The USB device's firmware contains all information about the device. A port is not reset until all descriptors in the firmware have been loaded and verified by the root hub. This is important because it applies to items such as printers and modems. Make sure that you have the most up-to-date firmware that is available for both your computer's BIOS and each device.
The symptoms of malfunctioning or incorrectly-configured firmware might be unusual. Typically, when you remove and then re-add a USB device, the device becomes available again. However, the device may be displayed as a second instance of that device, and load itself as such in Device Manager. If you see duplicates of a device, verify that you have the most up-to-date firmware for that device. This issue is common with USB printers and modems. A similar issue that has the same cause occurs when a device loads a device driver, and then adds a second device for which there seems to be no driver. The second device is displayed with an exclamation point in a yellow circle in Device Manager. The device may work correctly. However, you cannot remove the "ghost" device until you unplug the parent device that seems to have generated the ghost device. Also, you may be able to resolve this issue by updating the firmware or the device driver for that device.
New Version Of Windows? No Problem!
Upgrade smoothly by finding the correct drivers for your usb for any version of windows. For the first time, users can upgrade with confidence knowing that their computer will run smoothly thanks to the latest drivers and updates required for a perfect upgrade.
Why Updating Drivers Is Important
Usually the only reason we look to install or update usb drivers is because something is malfunctioning. This is not the only reason you should keep your drivers up to date however. VIA is constantly tuning and improving performance of their usbs and the only way to make use of this is by having the latest drivers. Going online and checking for new drivers all the time can be frustrating and is not an effective use of your time, and a simple tool like the driver installer above can keep all of your hardware running on the optimal drivers with top performance.
Sometimes when new hardware is installed, although it works correctly, other hardware which interacts with it may not be, because the other hardware actually needs its own drivers updated. This kind of co-dependency is another common problem and a reason why it's a great idea to have a tool that is constantly monitoring the state of all of your drivers and updating appropriately so you can upgrade and add or remove components in your computer while continuing to run without a hitch.
When your usb is relatively new, it may be possible to download individual drivers directly from VIA without incurring additional charges. If you are having problems locating the correct drivers for your usb, or are unsure of the exact model, we suggest you run a system scan first. It's very important you know the exact model of your VIA usb you would like to update to ensure that it will function properly and to prevent possible damage to your system. Download an installer that will automatically scan and identify your VIA usb to make sure you are installing the correct update and will also locate and download any additional driver and bios updates your pc may need.
