I find the usb emulation non-intuitive at best, and on a windows host, booting a virtual machine from a usb stick will be simply impossible due to timing issues. On windows hosts you insert your usb device and lauch vbox so vbox can detect the specific usb details and create a "dummy" passthru usb device node. then you remove your usb device, start your vm and then the usb passthru device is installed on the windows host, then and only then can you insert your usb device and have it seen inside the guest os. I can't see any practical method where this scenario would allow usb booting simply because it takes too long. (I can only assume that vbox on a linux host works similarly once you get your device permissions correct so that the vbox user/group can actually have access to the needed devices) Im content to netboot vm's anyway. so I'm not interested in usb booting. The one real problem with usb booting is a lack of bios consistency on this topic. Seems very difficult to me to emulate something on a vm that in all likelihood wont work on a real box.
