I think I can see the problem now, What it looks like happened is that I plugged in the USB adapter then put the CD in the drive to install the correct software.
But in the mean time Windows decides it will install its software and I go and install the software from the CD rom, Hence two lots on software installed for one device.
I have two icons on the system tray.
I can uninstall the software that came with through "Add/ Remove Programs" But cannot see any way of uninstalling the windows software, If I could find the registry keys I could remove it .
Any Idea's please.
