I saw in my 'device manager' that 'PCI simple communications controller' and 'USB IMAGING DEVICE' had yellow signs next to them, and when I checked it out, it said the drivers weren't installed. I tried to install them by the 'internet search' choice, and also 'searching' the hard drive, neither worked(It said the drivers couldn't be found.) Also, when I plug into the front USB port, a message comes up that says it isn't running at top speed, I should turn the port(s) into hi-speed ports. This is recent, previously, the device manager didn't show any issues, and the front ports were 3.0, hi-speed. What is the issue here, and where can I find the drivers to correct the problem, or is that the problem at all? Thanks!
