I am having problems getting my flash drive to show up in my windows virtual machine. I have used both fusion and parallels and have not been able to access my flash drive from within windows. Each time I plug in a flash drive, the virtual machine recognizes it and asks me if I want to use the flash drive in windows. I say, yes, but it doesn't show up and doesn't allow me to add files to it. Has anyone else had this problem? Any advice? thanks.
