Re: help for loading pwc module (solved)

[Beffe <beffe@beffe.de>]

Hi again,

i don't know if anybody reads this list, but i`ll tell you how i solved
my problem anyway. As i told you, usbmodules didn't find the pwc module
for my webcam allthough it is there in modules.usbmap.
Now the problem was that the function load_drivers didn't execute the
usb_map_modules function either cause it had the LISTER variable set.
So i simply had to change line 122 in hotplug.functions from 

   if [ "$LISTER" = "" ]; then

to 
   if [ "$LISTER" = "" -o "$DRIVERS" = "" ]; then

to let it execute usb_map_modules which finds the pwc module.



Another question:
in usb.agent you first call load_drivers with modules.usbmap, then you
call load_drivers with usb.handmap and last you call it with
usb.usermap, regardless if the prior call did already load a module.
Also, if load_modules has found a module, first it tries to load the
kernel module and then it executes the userscript.
In my opinion, if i have a userscript i would like to have it precedence
before the kernel module. That means that first load_drivers has to be
called with the usermap and it has to try to execute the userscript
before loading a kernel driver.
Also if there has been a driver found and loaded, why not just stop but
trying to find one or two more times a driver again? 
In my case, where usbmodules takes some 5 seconds on the webcam before
it cancels, this means about 15 seconds slowdown at boot time.

I would be really happy if one would answer. Maybe everybody is on
holiday?

Bye,
Beffe
