I have 4 USB ports. I have tried the phone in all of them. At present, only
one other port is in use. This is the mouse.
I have even tried removing all USB devices from the ports and removing the
USB stuff in device manager and then rebooting.
Once I plug in the phone again though, it is still detected as an unknown
device.

I have not tried using a hub because I do not have one. All the USB ports
are powered though.

I may have to give up and return the phone. It is of no use to me at
present.
