Hello guys I have recently upgraded from the Windows Vista to the Windows 7 32bit, everything was working fine but when inserted the pen drive and for which Windows perform automatic installation, but instead of reading the content on pen drive all the devices which were connected via USB port gone dead. And when I checked into the device manager all the “USB Root Hub” listings have a error code 19:” Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged.” Except one. And that one port which is not giving the error is notable as in its properties. The location of all the ports which are giving error is “on Standard OpenHCD USB Host Controller.” And the port without error has this location “on Standard Enhanced PCI to USB Host Controller”. Please help.
