|
| What's the difference between USB1.1, often referred to simply as USB, and USB2.0?
|
| The two are simply different standards of USB. USB 1.1 has been around for years and is often referred to simply as USB. USB2.0 is a new standard, which offers considerable speed increase over the earlier standard. To give you an idea of the speed difference, read this article.

| I have a PCI USB card with a VT83C572 chip. Where can I find the driver?
|
| Please use the USB filter patch.
|
| I have VIA USB port rev 5 or later and I have been told to update the drivers or the the controller
|
| This FAQ refers to USB 1.1 specification controller, not USB 2.0. For an explanation of the difference please read this. The VIA USB host controller, rev 5 or later refers to the version of the USB controller featured on your motherboard. The controller cannot be updated without updating your motherboard to a motherboard that has a later revision controller. The driver for VIA USB controllers are built into Microsoft operating systems which support USB. It is known as VIA Tech 3038 PCI to USB controller. This is inbuilt and cannot be updated. The advice you received to update the driver or controller, probably means that they recommend that you update the VIA 4in1 drivers. Or the advice might mean that they recommend you to install the USB filter patch. If you have been advised that you need revision 5 or later, but you have a revision older than 5, it may well be that the peripheral USB device you want to install is too new for your motherboard and therefore not compatible. If you suspect that might be the case, please ask for clarification from the manufacturer of the peripheral device.

| My USB devices stop working suddenly or will not work at all. |
1) Check that USB is enabled in your bios. Consult your motherboard manual
to see how to do this.
2) Windows 95, first edititon and Windows NT does not support USB. All other
operating systems have their own USB driver built in.
3) Check your motherboard manufacturer's web site to see if they have a BIOS
that provides more power to the USB.
4) Make sure that you do not have a device or many devices that require more
power than your USB port can supply. A standard onboard USB has 450 to 500 mA
of power (this is the USB standard). Examples of power used by USB devices:
Microsoft USB mouse - 100mA
Saitek Cyborg 3D joystick - 20mA
Kodak DC4800 camera - 2mA
USB network card - 180mA
Cannon Scanner N65OU uses 500mA of power just plugged in and up to 800mA when scanning
If all these USB devices are used at the one time they would need 1102mA of
power but the total provided by the motherboard USB is only 500mA. The only
way to use many USB devices at once is to get a Powered USB hub. A powered USB
hub uses 0mA and has up to 5000mA available. If you want to or need to use many
USB devices at a time, you have to get a powered hub. Some devices like scanners,
even on their own need a powered hub. They can run off the motherboard, but
it is not recommended if they use over 400mA.
To find out how much power your devices are using - go into System Properties
from Control Panel. Go into Device Manager under Hardware and under the tab
for Universal Serial Bus Controllers. Go into USB Root hub and look under power.
It will list the mA for devices plugged in. There will be a USB root hub for
every two ports you have available on your board. This will vary between 2 and
6.
5) Other things that will effect power to the USB are 1) BIOS settings made by motherboard manufacturers 2) Power Supply - an insufficient power supply will reduce power to the USB 3) CPU speed - the higher the power consumption of the CPU, the less power will be supplied to the USB and 4) the more peripherals you have in the PC will reduce the power to the USB

| Where can I get a VIA PCI to USB driver? |
| The VIA Tech 3038 PCI to USB controller is included in all Windows Operating systems that have support for USB. If your operating system cannot find the drivers, you will need to reinstall your operating system or contact the place of purchase of your PC for assistance. There is no update available for this driver, other than the driver provided with Microsoft Operating systems and service packs. |
| I cannot get my USB to work at all. Windows does not see any USB devices. What can I do? |
| Check that USB is enabled in your BIOS. Consult your motherboard manual to see how to do this. Windows 95, first edititon and Windows NT do not support USB. All other operating systems have their own USB driver built in. If your USB still does not work after you have enabled it in your BIOS, please contact your motherboard manufacturer. You may be required to update your BIOS. |
| In the USB1.10 filter patch, there is only a folder for Win98 and Win2K, what about other OS? |
| The filter driver will take care of all the necessary steps for all Microsoft operating systems that support USB. |
| I have a VIA chipset based motherboard and a USB Web Camera which freezes under Microsoft XP. What can I do?
|
General trouble shooting suggestions:
1) Ensure that you have USB enabled in BIOS.
2) Upgrade to the latest available BIOS.
3) Ensure that you are using XP compatible drivers and software for the web
camera.
4) If you have tried various versions of drivers and software, completely uninstall
the drivers and software and reinstall only the latest available versions so
there are no conflicts.
5) Try different USB ports.
6) Some programs have known issues with Windows XP WIA drivers. Information
can be found here.
7) Read this Microsoft
article on troubleshooting USB under XP for further advice.
8) If all of the above general troubleshooting have not resolved the issue
and you have a motherboard with KT133 chipset, buy a USB add-on card or use
a previous version of Microsoft operating system. If you have any other chipset,
contact your motherboard manufacturer and/or your web camera manufacturer for
further advice. If you have a KT133 based motherboard and all of the above general
troubleshooting have not resolved the issue, the reason we advise that you should
buy a USB add-on card or not use WinXP is because, at the time the KT133 chipset
went into mass production, many web cameras and Microsoft's Windows XP operating
system were not even available for compatibility testing. The vast majority
of motherboards based on the KT133 chipset work with new USB web cameras and
WinXP with no problems. Some motherboards, however, because of board design
and layout, are not compatible and the incompatibility cannot be resolved. VIA
appreciates that some end users may be unhappy about this situation. VIA and
our motherboard partners have stringent compatibility procedures, however no
manufacturer can guarantee compatibility with future products. Owners of these
motherboards will notice that they are not certified for use with Microsoft
XP.

| I have an external USB hard drive that features a VIA chip. Where can I get the VIA USB Peripheral Setup Wizard and VIA Button Triggered USB Copy Utility? |
| These applications may be distributed with some (but not all) USB hard drives that feature a VIA controller. These applications are only available from the manufacturer of the USB hard drive. They are not available for download from VIA Arena or from VIA's corporate web site. |
| Where can I get drivers for VIA 1394 IEEE Firewire controllers? |
Drivers for 1394 Firewire controllers are built into Microsoft Operating Systems and/or Service Packs. Make sure you have all of the latest Microsoft updates installed. |
| Where can I get Win2K/XP drivers for USB 2.0? |
USB 2.0 technology and drivers are subject to licensing by Microsoft (and other companies). This licensing means that they can only be distributed with new USB 2.0 devices and controllers, with Microsoft software, by Microsoft via the internet or by manufacturers of the USB 2.0 PCI card or device. VIA has of course worked with Microsoft and other manufacturers to develop driver support for VIA's VT6202 and VT6212 USB 2.0 controllers but due to licensing issues, the support for the drivers is the responsibility of device manufacturers, PCI card manufacturers & Microsoft.
- check the manufacturer's web site for an update
- complete Microsoft updates
- install VIS's USB 2.0 driver package that can provide additional compatibility support

| I get the message that there are no Hi-Speed USB controllers installed and I must add a Hi-Speed Host Controller to obtain maximum performance. |
| You must have a USB 2.0 device connected to a USB 1.1 port. Every time you turn on or re-connect that device you Windows will tell you that it could perform better with USB2 ports enabled. To stop receiving this message ... go to Start/Control panel/System/Hardware/Device manager and delete the device marked in yellow under other devices. |
