I think this is related to the shutting down mode of the newer Windows versions. By default, they do not switch off completely but enter only some Zombie state where some buffers are not flushed. I have forgotten how it is done, but it can be changed. I moved from VirtualBox to VMware because at that time (2 or 3 years ago) they had better USB support for virtual machines. I needed it for a tiny but excellent vector network analyzer. (that is not superfluous even sitting next to my VNB-8) It was possible to transport VMs from Virtual box to VMware without problems using this open virtual machine format. regards, Gerhard < http://sdr-kits.net/VNWA3_Description.html >
