Cable Modem Troubleshooting Tips
USB chipset driver updates
If use of cable modem through USB causes problems such as Windows crashes or freezes, you might need to update the drivers for the USB support chipset. To do this, you should visit the support site of the USB chipset manufacturer.
http://www.usbman.com/ has specific pointers for ALi, SiS, and VIA chipsets: scroll down the left-hand column looking for the heading
Host Type.
If your PC provides USB support with a VIA chipset (used on many Athlon motherboards), you might need to download updated
4-in-1 USB chipset drivers from
http://www.viaarena.com/, and you might also need the
USB Filter Patch from the same site. See also a VIA support site at
http://www.viahardware.com/.
Another option to consider is updating the BIOS on the motherboard: visit the support site of your PC manufacturer.
For further extensive advice on USB problems see
http://www.usbman.com/.
Windows XP and USB sleep/standby problems
If you have applied all the updates and patches referred to the article on USB chipset driver updates, and you still get occasional USB disconnections, it is possible that your USB cable modem driver is not smart enough to recover after XP has put the USB root hub into standby to save power. (VIA users note that the USB Filter Patch appears to address similar issues).
If drivers and patches don't fix this, you can prevent XP putting USB to sleep as follows:
Right-click My Computer and select Properties (or open control panel System).
Click tab Hardware, click button Device Manager.
Expand Universal Serial Bus controllers.
Double-click USB Root Hub (or right-click it and select Properties).
Click tab Power Management.
Uncheck Allow the computer to turn off this device to save power.
Click OK to exit USB Root Hub Properties.
Click the red cross to close Device Manager.
Click OK to close System Properties.
