Moved from "Website and Forum Discussions" Could someone please help me. I have exhausted every avenue available. When I put my flash disc into my computer. I get an error message. The device you are trying to connect to the virtual machine is being used by another application. Close that application or unplug the device and plug it again. Then try to connect the device again. Even my local computer expert can't work this out. This only happens when I plug the flash drive into the windows side of parallels.
