Have you tried asking this question on the shark forum? You may find you get a better response to this type of question on there as there will be a lot more shark users.

I have had the same problem with one of my laptops, a Lenovo. Even connecting often took many tries. I tried my wifes HP and it worked better. I purchased a refurbished Dell, as a backup and it connects the first time, every time, and never loses connection. My Lenovo(1 year old) already with a multitude of problems, decided to have the screen go out and crashed, so I replaced it with an Asus. It seems to be working the way it should connecting and maintaining the connection. My computer guy thinks it may be the manufacturers using different USB ports. The Lenovo never seemed to have a tight connection. The others do. Hope this helps. At least you know you're not the only one with this problem.

Dear Barry

We used to get 'missing coms' errors and stoppages on our Shopbot PRS Alpha. We traced it to some operators removing the USB memory stick (containing the part files) without using windows 'safely remove USB' option. Since insisting on the use of this procedure we have not had a 'missing coms' error and secure USB connections.

In good faith
Martin

PS The Shopbot uses a USB port as coms port
