With the SiS and Via, I often have to install the latest BIOS, then the latest Motheboard drivers. This is noted at http://www.usbman.com
Why Logitech notes SiS is simple. Many today expected Microsoft to fetch motherboard and USB drivers for us.
I just recently bought a Logitech ClickSmart 820 Webcam/Digital Camera, but it wasn't working on my computer. I tried it on my other computer and it worked fine, then I went to Logitech's website, it said that SiS Chipsets have problems with their cameras, and it listed how to solve the problem, the problem is, i don't understand any of what their saying, it says to change these settings in the bios, but i can't find any of them- Can anyone help me?
THIS IS WHAT IT SAYS:
If you are using a SIS? chipset, the following BIOS settings are recommended:
Plug and Play Operating System set to Enabled
Assign IRQ's set to AUTO
BIOS support for DMA set to Disabled (if this exists)
Write Prefetch set to Disable (if this exits)
USB Error Detection set to Disabled
Next, it is recommended to remove USB entries from the Device Manager. To do this:
Click the "Start" button.
Click on "Settings", then "Control Panel".
Double click on the "System" icon. Windows 2000 users, click on the Hardware Tab.
Click on the "Device Manager" tab.
Click on the plus (+) sign next to "Universal serial bus controller".
Highlight the first entry listed under Universal serial bus controller.
Click the Remove button and confirm the device removal.
Repeat steps 6 and 7 for each entry under this section.
Close the Device Manager and reboot.
Additionally, you may need to change the SIS Host Controller driver to a Standard OHCI USB Host Controller, as described above.
