Windows se vasta sekoileekin noiden kanssa. Kokeileppa läppärissä vaikkapa WLAN kortilla tyrkätä se eri PCMCIA korttipaikkaan kuin missä se on ennen ollut, Winsucs löytää "uuden laitteen" ja asennuttaa sen uudestaan kaikkine asetuksineen vaikka kysessä on jo kertaalleen asennettu ja konffattu kortti. Sama sekoilu USB laitteiden kanssa, hemmetinmoinen homma Winsekoilun kanssa muistaa että mihin PCMCIA/USB paikkaan mikäkin laite on asennettu ettei tyrkkää väärään paikkaan...

on tätä etsitty, vaan löytyhän se ratkaisu.
Nyt kun tyrkkään kameran koneeseen kiinni se tunnistuu ja mounttautuu /mnt/usb kansioon ja kun sammutan kameran se unmounttautuu.

Tässä ohjeet.

1. /etc/udev/rules.d kansioon seuraava sääntö

KERNEL=="sd*|sr*|ub*", ACTION=="add", SUBSYSTEMS=="usb", ENV{DEVFLAG}="usbdisk", NAME="%k", GROUP="cdrom", MODE="0660", RUN+="/lib/udev/usbmount.sh add /dev/%k"
KERNEL=="sd*|sr*|ub*", ACTION=="remove", ENV{DEVFLAG}=="usbdisk", RUN+="/lib/udev/usbmount.sh remove /dev/%k"

2. ja /lib/udev kansioon usbmount.sh skripti

VERBOSE="no"

log()
{
[ "$VERBOSE" = "yes" ] && logger -p user.$1 -t "usbmount[$$]" -- "$2"
}

in_list()
{
for v in $2; do
test "$1" != "$v" || return 0
done
return 1
}


test -x /lib/udev/vol_id || { log err "cannnot execute /lib/udev/vol_id"; exit 1; }

sitten vaaan /etc/rc.d/rc.udev restart ja kamera tunnistuu.
