So apparently the "universal" part of USB has an asterisk beside it. I set up my mother's new computer for her on the weekend, and everything was going tickety-boo (well, aside from training my mother, that is ... but that's a whole other issue!). Until I got to the printer, an ancient Lexmark inkjet. Windows 8 didn't have the driver for it automatically, but I was able to get it online. But after installing it, I tried to print something -- and nada. Went through the Windows trouble-shooting process and got an error message along the lines of "some USB 2.0 peripherals are not compatible with USB 3.0." WTF? I've googled about 8 different wordings of the problem and have not come up with anything remotely helpful. Any suggestions? Is there any way of fooling one of the USB 3.0 ports into thinking it's a USB 2? Will a hub work? A different printer cord? Anything ?? TIA.
