 Supplemental info.
 
 I repeated these tests twice.
 
 Reboot.
 'startx' for XFCE.
 
 Before suspend:
 $ ps auxwww|grep mouse
 root       1296   0.0  0.1  9608 1456 ??  Is    9:26AM 0:00.10
 /usr/sbin/moused -p /dev/ums0 -t auto -I /var/run/moused.ums0.pid
 root       1671   0.0  0.1  9608 1500 ??  Ss    9:26AM 0:00.01
 /usr/sbin/moused -p /dev/psm0 -t auto
 root       1796   0.0  0.2 12244 3176 ??  I     9:26AM 0:00.02
 hald-addon-mouse-sysmouse: /dev/psm0 (hald-addon-mouse-sy)
 root       1824   0.0  0.2 12244 3184 ??  I     9:26AM 0:00.01
 hald-addon-mouse-sysmouse: /dev/ums0 (hald-addon-mouse-sy)
 
 Trial 1
 -------
 Suspend (XFCE panel: menu: user JB - Suspend)
 
 Resume (power switch ON).
 
 After resume:
 $ ps auxwww|grep mouse
 root       1671   0.0  0.1   9608   1500 ??  Ss    9:27AM  0:00.79
 /usr/sbin/moused -p /dev/psm0 -t auto
 root       1796   0.0  0.2  12244   3176 ??  I     9:27AM  0:00.02
 hald-addon-mouse-sysmouse: /dev/psm0 (hald-addon-mouse-sy)
 root       2007   0.0  0.1   9608   1556 ??  Is    9:32AM  0:00.07
 /usr/sbin/moused -p /dev/ums0 -t auto -I /var/run/moused.ums0.pid
 root       2063   0.0  0.2  12244   3452 ??  I     9:33AM  0:00.01
 hald-addon-mouse-sysmouse: /dev/ums0 (hald-addon-mouse-sy)
 
 Note:
 - first suspend/resume seems to work OK (both mouses work).
 - the moused PIDs are different for USB mouse (1296 -> 2007)
 
 Trial 2
 -------
 Suspend (XFCE panel: menu: user JB - Suspend)
 
 Resume (power switch ON).
 
 After resume:
 $ ps auxwww|grep mouse
 root       1671   0.0  0.1   9608   1500 ??  Ss    9:27AM  0:00.93
 /usr/sbin/moused -p /dev/psm0 -t auto
 root       1796   0.0  0.2  12244   3176 ??  I     9:28AM  0:00.02
 hald-addon-mouse-sysmouse: /dev/psm0 (hald-addon-mouse-sy)
 
 Note:
 - second suspend/resume blocks USB mouse
 - neither HAL nor moused processes present
