Peter Anvin (author of isolinux, etc) There is a wide variety of BIOS implementations out there when it comes to usb boot support, and the inconsistency has caused the syslinux project NOT to pursue usb booting officially yet (maybe ever) I believe the same BIOS variety would impact vbox as well. They of course write their own bios, but that makes vbox not as useful as a testbed/dev platform when you know that what you can do in vbox you cant do on any given real box. As to your question about permissions on ubuntu check into your udev configuration file. udev creates the device nodes for usb devices as they are detected and udev can be configured to make those device nodes with specified permissions so that they can then be used by any given user/group. I suggest you start there. vbox on linux must run as the user that started vbox and with group privs assigned to the vbox group. fix udev to make new usb device nodes with at least read/write user:group permissions, and owned by root:vbox and that should fix your device permission problem.
