Hotplug problem while cold-pluging
Hello there,
I just subscribed the mailing list for this special question because I
can't solve a recent problem while changing from kernel 2.4.21 to 2.6.2.
It concerns the cold-plug phase of the hotplug scripts, and, though I
would find some related talks about the subject in various other mailing
lists archives, none could really help me understand precisely what is
going wrong.
I also tried to fix it up by myself by editing the scripts in
/etc/hotplug but ended up on a "FIXME" commented line which seems to
mean that the functionality I require may not be fully implemented yet.
It says that PRODUCT and DEVICE variable are not adequately set (which
is true, and seems to be the origin of my problem)
Well here's the story:
I have a sagem f@st800 dsl modem hooked up on an usb port. The drivers
do not ship with debian packages so I compiled them myself from sources
and installed the kernel module in /lib/modules/etc... I first used some
scripts provided with the source code to fully install the device but I
finally ended up doing it my own may as those scripts were not verbose
enough for something I run with 'root' privileges (i.e.: I want to not
WHAT is going WHERE when I mess up with my Debian !).
Then, there is a script in /etc/hotplug/usb/ that should be executed and
that downloads firmware to the modem. It is mandatory before anything else.
Of course, I edited the usb.usermap file and it looks ok (as you will see)
Now if I unplug, the plug the deviceback , everything is OK. The driver
is loaded, the script is called, the UNPLUGSCRIPT is registered and
called if i unplug the device again... It really works great... This is
why I believe the script that loads the firmware is working and that the
usb.usermap file is well formed.
but,
Nothing happen when I boot up the computer. You can easily undestand
that in case of a power outage, I really need the modem to get back on
line without someon unplugging then plugging back the usb plug !
see that's pretty anyoing stuff...
Are there any hotplug cracks here ?
BTW, hotplug sees my modem during coldplug but does not call the
adequate script. During this coldplug phase, all PRODUCT strings are
"0/0/0" which surely does not help loading the good driver... but the
usb.rc script defines them like this.
Well I'm stuck... any idea or more recent script welcome.
I'm running a 2.6.2 kernel with devfs support, /proc support, /sys
filesystem, and usb fs support as well... I must admit that I am quite
confused by all this mess around with /sy/bus/usb, /proc/bus/usb and so
on... many things seems duplicated, and... well It is was more clear to
me, I guess I would not request for help ! ?
;o)
many thanx in advance
