Get it right, then make it fast.  Don't try to make it fast until it's
right -- that way lies madness.

:)  Right.  But why not have the autoprobe go ahead and modify the
qcam.conf file?  Here's the "right" algorithm for qcam-lib:

Default to 0 (autoprobe)
read qcam.conf
read command-line's -p switch
if zero, read each port in turn.
If not found, write a reset to each port in turn.
If still not found, give up.

And the probe program just takes the resultant value and writes it
into qcam.conf.  Seems like that gives the desired behavior in all
cases.
