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
