the above title explains the problem. Have followed troubleshooting guide, tried to re-install device driver, message that there is a problem with PnP devices. attempted Installation of device driver fails. Message: "Best driver already installed & MS has determined driver is up-to-date." At one point received message, "please consult with our device manufacturer for assistance getting this device installed." also, "device driver software was not properly installed." I have installed no new hardware in a number of months; my printers were working fine 2 hours ago, now they will not print. I use a hub to connect 2 printers & MS mouse to Toshiba Satellite laptop which is almost 3 years old. Came with Vista and a free upgrade to Win 7, 32 bit, I think??? Installed Win 7 over 2 yrs ago....no previous problem with this type of situation. Please help!
