Hmmm, the permissions stay for me. I too struggled to get USB to work, it seems to be pretty lacking with Linux support in VirtualBox, which is a big downfall. Although, I had a lot of issues with permissions with VMware Server as well when I ran it. I guess pick your poison. This process works for me though, so I'm not sure what else to suggest to help you out. Regards, Max
