I have recently purchased two new laptop computers, a Toshiba Tecra and an HP. Boith are experiencing similar problems of blue screening when I plug in USB memory sticks or digital video card readers. It is not consistent. Sometimes, it is OK and other times I get the blue screen. There seems to be no common problem.
I have reformated the memory stick. When I use it on other desk top computers, no problem, just when I use the laptops. I have tried four different memory sticks to see if I might have a defective one but get the same results with all of them.
