Windows 7 what causes the 'USB no recognised"

I have not tried this myself, but I noticed, in the Device Manager, if you look at the properties for the USB Hubs, there is a Reset Hub option on the Advanced tab.

You will have to find the correct one, but it may help.

Have you tried plugging the device into another port?

yes thanks - it worked in other ones.
then the computer died to blue screen.
so i unplugged some things unplugged the computer - as directed!
so it is okay.
