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?
