No, umass devices show up in /dev as /dev/da[n] for disks and USB keys, /dev/cd[n] for CD-ROMs. The permissions on these devices are independent of the permissions on /dev/usb. These are the permissiosn when I plug in my USB key: crw-rw-r-- 1 root operator 241, 255 Nov 5 15:38 /dev/usb crw-rw-r-- 1 root operator 241, 0 Nov 5 15:38 /dev/usb0 crw-rw-r-- 1 root operator 241, 1 Nov 5 15:38 /dev/usb1 crw-rw-r-- 1 root operator 241, 2 Nov 5 15:38 /dev/usb2 crw-r----- 1 root operator 229, 17 Nov 5 15:38 /dev/da0 crw-r----- 1 root operator 229, 19 Nov 5 15:38 /dev/da0a crw-r----- 1 root operator 229, 20 Nov 5 15:38 /dev/da0c crw-r----- 1 root operator 229, 18 Nov 5 15:38 /dev/da0s1 -- Craig Rodrigues http://crodrigues.org rodrigc@crodrigues.org
