My output:
cat /etc/group | grep usb
usb:x:502:reno
I can make a group usb which contains user reno and

There is no /proc/bus/usb within my /etc/fstab file,
instead, there is:
none /proc proc defaults 0 0

none /proc/bus/usb usbfs
devuid=0,devgid=1002,devmode=0660 0 0
within the /etc/fstab.

reno.
