Idea. What, exactly, are you trying to achieve?
Oh, I was just looking for another way of configuring my device driver
from user space. The sysctl mechanism was suggested by a gentlemen a few
days ago. But I don't believe it will work in my situation. This device
is one of a series. Several devices of the same model can be connected on
a single system. And there is no way of identifying each device uniquely,
other than USB address. So I would need a set of settings for every
(model, USB address). I don't see sysctl being applicable here. Tell me
if I'm wrong. I just thought it might be easier to have the configuration
done via a pipe or message queue. Any suggestions?
