1. Search for virtualbox group id, make sure you already put your username under vboxusers group:
$ cat /etc/group
..
vboxusers:x:122:kumkum
..
2. Add this line to /etc/fstab:
none /proc/bus/usb usbfs devgid=122,devmode=664 0 0
3. Reboot system. Finish. Try plug your usb device to VirtualBox.
Note:
– devgid=122 is vboxusers group id which is taken from /etc/group
– USB is not supported in VirtualBox-Open Source Edition
