ho trovato questa soluzione

lanciare questo comando
$ strace xsane 2>&1 | grep EACCES
open("/dev/bus/usb/005/001", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/005/001", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/007/004", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/007/003", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/007/001", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/007/004", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/007/003", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/007/001", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/002/001", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/002/001", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/003/002", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/003/001", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/003/002", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/003/001", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/004/001", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/004/001", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/001/001", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/001/001", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/005/001", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/007/004", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/007/003", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/007/001", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/002/001", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/003/002", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/003/001", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/004/001", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/bus/usb/001/001", O_RDWR)    = -1 EACCES (Permission denied)
open("/dev/port", O_RDWR|O_NOCTTY)      = -1 EACCES (Permission denied)

tutte directory sono come le seguenti
/dev/bus/usb/006# ls -l
totale 0
crw-rw-r-- 1 root root 189, 640 16 apr 23:20 001
crw-rw-r-- 1 root root 189, 641 16 apr 23:20 002
crw-rw-r-- 1 root root 189, 642 16 apr 23:20 003
crw-rw-r-- 1 root root 189, 643 16 apr 23:20 004
crw-rw-r-- 1 root root 189, 644 16 apr 23:20 005

pensavo a questo comando
# chmod a+rw name-directories

ma ci possono essere altri modi?
problemi con la sicurezza?
