Re: Dimension 4500, Universal Serial Bus error and SM Bus Controller Error, They both show up with errors in device manager, HELP

I have got exactly the same issue with the SM Bus controller. The USB one went away by allowing XP to look on the internet for the appropriate driver, but I cannot find out what the SM Bus controller is. I thought it might be something I have installed, but since you have the same issue that is unlikely. Have written to Dell tech support to see if they have any answers??
