Im having an issue with installing USB devices on a Dell Inspiron N4030 running Windows 7 Home Premium. Whenever I plug in a new USB device it tells me that the device failed to install, when I look at the device manager it gives me the error code "device drivers not installed (Code 28)" This is happening with all USB devices on this computer. I have tried system restore, deleting and repopulating the INFCACHE.1 file and still get the error any help on this would be great, im about to reinstall Windows
