Paul's Unofficial ABIT KT7 FAQ
for the KT7, KT7A, KT7-RAID and KT7A-RAID motherboards
C Paul E Howland, 2000-2001

Why don't my USB devices work?
A number of people experience problems with USB on motherboards using =
the VIA KT133 chipset, although these are not easily reproducible. The =
problems are therefore likely to be due to a number of cumulative =
problems. I therefore recommend the following:

  1.. Enable an IRQ for USB in the BIOS=20
  2.. Install VIA's USB Filter Driver=20
  3.. Set "K7 CLK_CTL" as "default" instead of "optimal" in the =
"Advanced Chipset Features" submenu of the BIOS. This has no impact on =
performance and has solved the USB problem for most users. (This BIOS =
setting is not available in BIOS WW)=20
  4.. Try setting "Enhance Chip Performance" on both enabled and =
disabled in SoftMenuIII of the BIOS. The USBMan has worked with two =
independent manufacturers and found that enabling this option resolves =
many USB problems on the KT7 series of boards - see his ABIT page for =
details.=20
  5.. Do you have peripherals in PCI slots 4 or 6? These share an IRQ =
with the USB controller and so moving devices out of these slots, or =
swapping a different device into the slot if all your slots are used, =
may resolve problems.=20
  6.. Make sure you have an adequate power supply (at least 300W)=20
  7.. Try modifying your memory settings (slower or faster) - this has =
helped many people.=20
  8.. Get better quality memory (several users have solved USB problems =
by replacing generic RAM with Crucial or Mushkin brands)=20
  9.. Some users have reported v4.25 of the 4in1 drivers solved USB =
problems - see drivers section for link=20
  10.. There is a known bug in the Universal Host Controller driver =
(Uhcd.sys) shipped with Windows 98SE that causes problems with the VIA =
chipset. Microsoft have a patch for this available at their support site =
under Q240075.=20
  11.. Read the Microsoft Knowledge Base article entitled General USB =
Troubleshooting in Windows 98, Windows 98 Second Edition, and Windows =
Me. This includes many tips and links to several other related =
Knowledge Base articles.=20
  12.. Try ticking "disable USB error detection" in Device Manager under =
Universal Serial Bus controllers, PCI to USB Universal Host Controller=20
  13.. Does your USB device load on a port exceed the power handling =
capability of the onboard USB controller? This may be the case with =
devices such as USB cameras, in which case purchasing a powered USB hub =
would help.=20
  14.. Problems often arise if you are trying to run your memory too =
aggressively - try relaxing your memory settings (see memory section). =
Try disabling Force 4-way Interleave and Enable DRAM 4k-Page Mode in =
SoftMenuIII=20
Other reported solutions include:

  1.. Setting CPU Drive Strength to 3 and enabling Enhance Chip =
Performance=20
  2.. Contrary to the advice above, one user reported solving his USB =
problems by uninstalling the VIA USB filter driver! Try it and see =
(otherwise reinstall)!=20
  3.. One user reported disabling his Soundblaster by ticking "Disable =
in this hardware profile" in Device Manager whilst scanning, etc, =
resolved the problem=20
  4.. Some users with a KT7-RAID have reported having a disk installed =
on Highpoint Secondary controller caused USB disconnects=20
  5.. One user found USB instabilities were due to SB16 emulation being =
enabled on his MX300 soundcard=20
  6.. One user reported problems with an HP USB Scanjet scanner failing =
to work. Even replacing with another HP Scanjet had the same =
difficulties, but on replacing it with another brand his problems were =
resolved=20
  7.. One user with an ABIT KA7 motherboard found that his USB solutions =
were due to using a 3Com 3c905TX PCI network card. On using a different =
NIC (in the same slot) the problem was solved. The D-Link DFE-530TX PCI =
and the 3Com 3c509B ISA network cards did not cause USB problems. Let me =
know if this problem occurs on your KT7!=20
  8.. One user explained that all of the following were required to =
achieve consistent USB stability on his machine:=20
    1.. The Highpoint drivers default the minimum and maximum cache to =
0kB. Using a cache setting program such as RAM Idle SE, increase the =
max cache to 6140kB. =20
    2.. In WindowsMe go to Control Panel and Scheduled Tasks and disable =
the PC health task, this kicks in every 5 minutes or so and occasionally =
kicks out the USB devices. =20
    3.. Set the CPU drive strength at 3=20
    4.. In Properties, Advanced of the USB Universal Host Controller, =
disable USB Error Detection. This can be found under System =
Properties, Device Manager, Universal Serial Bus controllers, USB =
Universal Host Controller.=20
    5.. Also set I/O voltage to 3.3 or below and CPU voltage no higher =
than 1.80v. =20
    6.. Absolutely no FSB overclocking as this can make the devices =
unstable!! =20
    7.. Do not install the VIA USB filter driver in WindowsMe and =20
    8.. Install the Via 4.25a drivers with AGP4 disabled in the bios =
first, then re enable it afterwards.=20
For other USB problems try the usbman website and the VIA USB - Tip and =
Tricks page in particular.
