Re: Gphoto2: Could not claim the USB device
bones!
crec que el problema que tens està relacionat amb la manera com hotplug
tracta els dispositius que hi vas afegint. cada vegada que endolles la
càmera ell crea un directori de nom aleatori on ell gestiona el
dispositiu. llavors el que s'ha de fer és un petit script que doni
permisos sobre aquest directori, aquests scripts es fican a
/etc/hotplug/usb
hauries de crear un grup usb (si no el tens ja) i afegir-hi els usuaris
que vulguis que puguin accedir a la càmera. després crea aquest script:
=======================================8<=============================
#!/bin/bash
# http://www.gphoto.org/doc/manual/permissions-usb.html
# afegeix el grup usb si no existeix!!!
case $ACTION in
add)
if [ "${ACTION}" = "add" ] && [ -f "${DEVICE}" ]
then
chgrp usb "${DEVICE}"
chmod g+rw "${DEVICE}"
fi
echo "camara endollada"
ogg123 /home/muzzol/confs/sons/on01.ogg
;;
remove)
echo "camera desendollada"
ogg123 /home/muzzol/confs/sons/off.ogg
;;
esac
=======================================8<=============================
el deses com a usbcam al directori que he dit abans. pots comentar o
canviar el so, jo ho trobo bastant útil perqué així saps si realment ha
pillat la càmera o no. una vegada fet això no hauries de tenir cap
problema.
fins ara
