Been working on this for two days followed all the posts I could find: - Uncommented Magic section in /etc/init.d/mountdevsubfs.sh - Added group to usbfs /etc/udev/rules.d/40-permissions.rules w/perms of 0666 - Added ""none /proc/bus/usb usbfs devgid=1001,devmode=666 0 0"" to /etc/fstab - And...rebooted everything many times I was receiving an error of ""Could not find a USB device with UUID"" in my VBox.log, however, I noticed the devgid in /etc/fstab was different then my vboxusers group...after making this the same in fstab I'm not longer getting the Could not find a USB device error. Other then that logs looks relatively clean. I have attached all available Vbox logs Tried plugging in an I/O Magic USB HD and it worked fine...guest recognized and mounted it no problems. When I plug Sansa in with out VBox running Ubuntu recognizes it and mounts it no problems. Device shows as connected and VBoxManage list usbhost shows state as Busy. $ VBoxManage list usbhost VirtualBox Command Line Management Interface Version 1.5.2 (C) 2005-2007 innotek GmbH All rights reserved.
