USB flash card reader problem

I have a digital Kodak camera that uses flash cards and a USB card reader. Ordinarily, whem I plug the card reader into a USB port, windows recognizes it, and it appears as disc "I" in my computer, and anywhere there is a file tree. Lately, when I plug it in, windows makes the usual "plunk" sound, but it does not ask me what I want to do. Nor does the "I" drive appear anywhere other than in disc management. From there I managed to view the contents, but I got the blue screen several times on the way. Windows tells me that all my drivers are fine. I'm stumped. What am I missing? Thanks.

 

Did you remove it once without stopping it first???

 

I probably did. Since the problem started, I have also reinstalled the drivers several times
