Re: [Linux-gpib-general] Problems with NI GPIB-USB-HS

[Riccardo <r.d...@ti...>]

I tought that gpib_config is launched by the hotplug script. In
/etc/hotplug/usb/ni_usb_gpib there are the lines:


GPIB_CONFIG_OPTIONS="--minor 0"

case $PRODUCT in

# ni-usb-hs
3923/709b/*)
        gpib_config $GPIB_CONFIG_OPTIONS
        ;;


I'll try to verify that this script is correctly loaded. On the other
hand maybe I have to specify more option on gpib_config to fit my
interface, but I could not find more information about it.
