Dear Sirs,
I found the following strange behaviour. My Nettop has an internal
Samsung umodem, but I need a umsm. If the second modem (and hence
both) is pluged and I boot, then umsm is not attached to a com, I
need to unplug and plug again.
Perhaps someone has an Idea of a non-mechanical way of getting it
attached to a ucom. Not a solution, but for the meantime.
Below some dmesgs.
Rodrigo.
