Hello all, I am new to the forum.

 

I have been using a USB720 modem card to connect to the internet w/ laptop. Suddenly  it stopped working, and it doesn't recognize the USB720 card at all when plugged into the USB port. It says the device is not recognized, and possibly malfunctioned. It says to try to reconnect the device but I have tried several times with no luck. I apologize if this topic is already somewhere else, if so .. please direct me! I've tried system restore with no luck. (It has been working fine for quite some time now) Do I need to reinstall a driver for it perhaps? Any help is greatly apprecicated!

 

Thanks!
