Sony VGN-TZ31WN_B running USB 1 not USB 2
Posted on 2011-05-03
Whenever I plug in a USB drive into my laptop (several drives) I get the warning message that my USB devices are running at USB 1.1 speeds and not USB 2.0.
I have looked on the Sony website and there are no USB driver updates. I have done all the Windows updates, as well as deleting my USB devices under System, and then I did a hardware scan but my USB devices still run at USB 1.1.
can anyone help with this please?
