I've had a 7 port rosewill usb hub connected to my computer for about a year now, and all of a sudden the other night it stopped working. Windows will no longer recognize it, and calls it an unknown device. It gives me the error 43, but so far uninstalling the usb devices hasn't seemed to work. I've only been able to uninstall one of the devices though, because as soon as I do that my keyboard and mouse stop working. I know the hub isn't broken, it works on every other computer, so it has to be something in windows. Any ideas?
