There is highly interesting setting in virtual machine preferences: USB, When new USB device is plugged into your Mac while this v.m. is running
connect to this virtual machine.
The feature is interesting from amongst others following perspective. If the external drive is infected by some
bad stuff, it is good the host OS does not get in touch with it until the guest, because in our env. the av scanners
run on guest, not on host.
1. How much the host OS get's in touch with file system on USB external drive when this setting is ON?
2. Any chance to have similar setting on detaching usb device from guest, means do not allow the host to mount volumes
on the external but let it to do Eject.
