Gidday Forum Folk. It may be a coincidence but after updating to OSX.4.9 I now get the following error message on Windows virtual USB device you are trying to connect to the virtual machine is being used by another process Wait 5-10 seconds then try again if not find application that blocked up the device & disconnect it manually". It has no problem with my printer, but gives the message to my camera, & two different memory sticks, all; of which worked before. The only thing I notice is that the stick icon appears on Mac window ?? Any ideas out there.
