By default, all hard drive and usb drive devices belong to group "disk". I want to change usb drives to group "adm".
I verified the ID_BUS
$ udevadm info -q all -n /dev/sdb | grep ID_BUS E: ID_BUS=usb
I created the file /etc/udev/rules.d/70-persistent-usb.rules and insert the following
# Enable admin controls on all usb devices. ID_BUS=="usb", GROUP="adm"
Lastly, I disconnected my usb drive and reconnected it. It is still showing
$ ll /dev/sdb brw-rw---- 1 root disk 8, 16 Apr 14 19:31 /dev/sdb
The drive group is not "adm"? What am I doing wrong?
