Getting Started
Troubleshooting
VIA USB
- Update the BIOS to the most recent final
release (non-Beta) revision.
- The BIOS must be properly configured
- USB MUST be Enabled in the BIOS (USB keyboard
is Enabled and/or Legacy USB is installed)
- BIOS Chip Performance Speed -
Normal
or Enhanced Chip
Performance - Enabled
- USB does NOT like to share its IRQ with
another device.
- AMD Systems NEED Approved Supplies
- NO exclamations marks should appear next to
USB in Windows Device Manager
- Windows IRQ Steering should not be
displaying errors
- Installing the latest version of the VIA
Hyperion 4 in
1 Driver is a good place to start.

Operating
System Specific
Win95 v.B & C Only (Copied
from the
VIA Q & A recently pulled from the VIA web site)
- Q: Are there any USB drivers for Windows 95?
A: We do not have any drivers for Win 95 because of it's limited USB
support. For the best USB performance, we suggest upgrading to Windows 98
or later. If you want to continue using Win 95, we suggest using the
default drivers. You must have Win 95 OSR2 version or later.
Win98 First Edition
- VIA IRQ Routing Driver
for
Windows
98 First Edition Only. Try
this before installing the Service Pack
- On older VIA chipset based motherboards,
(Socket 7), running Win98 First Edition, (also known as Windows
Gold Edition), you may see better results if you DO NOT update
Internet Explorer or install the Win98 Service Pack. If you have completed
the other steps in this guide and USB is still not working properly install the Win98
Service Pack.
Win98SE Patch for VIA and AMD processors over 350 MHz

Windows
2000 Drivers
Quote from the VIA Web Site: "Microsoft® has incorporated VIA drivers into
the Windows® 2000. Some users may be experiencing limited USB support with
Windows® 2000. This problem will be corrected with a USB filter driver which
enables Windows® 2000 to detect USB peripherals with VIA chipsets. The USB
Filter driver is under development and will be posted on our website upon
completion. VIA apologizes for any inconvenience."

BIOS Update
Correct BIOS Settings (Generic
Instructions)
- Power Management - Disabled

(Disabling Plug and Play OS can cause errors in Windows IRQ
Steering). Some systems may perform better with this option Disabled.
Try both if you are having IRQ problems.
- IRQ's Assigned - Auto

MVP3. Use the VIA drivers further down this page.
Installing the Drivers for VIA based
motherboards
- You MUST install the IRQ Routing,
IDE BusMaster, INF and
latest AGP device drivers for all Windows Operating Systems. All necessary drivers except the
USB Filter are included in the New VIA Hyperion 4 in 1
driver.

Please do not get confused which type of USB controller you have.
This article should clarify any questions you may

Filter Driver Confusion.
What to Do - Installing the USB Filter Driver - Yes
or No
- Try to get your system working without
installing the USB Filter.
- Adjust the BIOS settings (Your
best chance)
- Follow all of the troubleshooting steps
- Install OS and/or Chipset specific
patches if applicable.
- If USB is still not working, install the USB Filter Driver
- The exception to this rule is the KT266
based motherboard. Install the New
74 Patch.zip for all KT266 Mainboards. This
above New 74 Patch is for KT266 based motherboards ONLY.
Note:
- The USB Filter Driver is NOT included
in the 4 in 1 Driver File.
- You MUST install the 4 in 1 Drivers
before the USB Filter Driver. (All Windows Operating Systems
EXCEPT WinXP)
VIA PCI Latency Patch
- VIA Chipsets have a known issue with PCI
Latency. Although, specifically developed for IDE and sound problems
with VIA chipsets, users have reported improved performance in other areas
including USB and video capture. If USB is otherwise working correctly
but, not a fast as you would expect, try the patch from VIA Hardware

Motherboards, Software and
Other Fixes
-
USB works sporadically, hangs or
locks the system
-
Timing Issues with VIA
Chipset based motherboards can sometimes be fixed by setting the chip
performance speed in the BIOS to Normal instead of
Strong, Turbo, Optimal or Fast.
The setting title and location varies by manufacturer and board type.
-
Make sure that your Power
Supply is AMD certified
-
Check to see if USB is
sharing its IRQ with another device
-
USB does NOT like to
share its IRQ. If USB is sharing its IRQ with another device
you will need to isolate USB so that it has its own IRQ
-
Please
Note: Windows will NOT report USB IRQ sharing
violations even if one exists. To determine if USB is sharing
its IRQ use, System Information / Conflicts and Sharing
-
Update to the latest BIOS
version for your motherboard
-
Check the following BIOS
settings for True
-
PCI to DRAM Prefetch => Disabled
-
System Performance => Normal
-
PCI Master Read Caching
=> Disabled
-
Delayed Transaction => Disabled
-
PCI Master Time-Out => 0
-
K7 CLK_CTL => Default
-
P2C/C2P Concurrency => Disabled
-
Plug&Play OS Installed
=> No
-
Reset Configuration Data
=> Enabled
-
Additional Help
- Web Cams / WinXP
/ KT133 boards
-
Solution
- Install a PCI/USB card. Disable onboard USB function in the
BIOS
-
Tip - Choose a card
from the tested and
approved page. There is a thread on the VIA
Arena Forum that makes interesting reading. So far this is
the only known fix. VIA, brand new chipset, same old problem.

USB Keyboard/Mouse Installation Guide for Red
Hat Linux 7.2/7. 1.
This document describes how to enable USB
keyboard/mouse, topics covering (1) using USB keyboard/mouse for OS
installation, (2) hot-plugging USB keyboard/mouse, and (3) using PS/2 and
USB mice at the same time.

Last Resort
So you've done all the above and
still no USB. Check in the Special Section for specific fixes.
If still no good, a tested and approved USB/PCI card will usually do the
trick. Follow the link and read all the information before you
buy a card.
- Install a OPTi or Lucent chipset based PCI/USB Card in an available PCI slot
if you need additional USB 1.1 ports. If you wish to upgrade to USB
2.0, buy a card with an NEC chipset. Keep in mind that USB 2.0 cards
require (2) additional IRQs and work best when installed in a PCI slot that
does NOT share an IRQ with any other
device. Choose from the list of USBMan
Tested and Approved Upgrade
Cards by Manufacturer and Chipset. DO NOT buy a VIA based PCI/USB card
testing has proved them to be unreliable on systems with existing USB
problems
