What should I do if my UF software shows that the dongle cannot be found
You can first unplug the dongle and plug it in several times. If it is a desktop computer, plug it into the USB port on the back of the host and try it. If it can't be recognized, the dongle may be broken. Check the registration code of the dongle to see if it has an expiration date. If there is an expiration date, it cannot be used after it expires. Take a look at the driver If the above-mentioned methods still do not work, you can only find UF for maintenance. Of course, you must find a formal authorization.
