[Voyage-linux] QB9 and some earlier silly questions of mine

First, about my first posting to this list:
Thanks to Frank for reminding me to do an apt-get update to initialize the
database. I found the init script (voyage-util) which sets the root
directory to ro; I was grepping for a string which did not have the caps
right :-<.
Most importantly, I discovered that whether the QB9 works or not
with its USB2.0 setting is very dependent on sequencing. For me, on two
machines running voyage, if you power up the QB9 with the USB connected,
it does NOT work; one gets the ubiquitous
ALSA clock.c:227: 4:1:1: cannot get frequency at ep 0x1
and the display immediately comes up "96", and it will not play
anything.
If, on the other hand, you plug in the USB with voyage running and
the QB9 powered and running, it works fine. I will keep you posted
on further developments. One of the machines, a mini-itx with
a Zotac M880G motherboard, is running 7.0; the other, an old
VIA C7 mini-itx, is running the slightly more recent current version
I downloaded a couple of days ago; I do not think there are significant
changes from 7.0, but Punky could comment.
I have had nutty troubles with mpd building the database from scratch;
the music on both machines is on a local disk, and I just make a symlink
called music in /var/lib/mpd to a directory which contains symlinks to
the real music directories, organized one directory per album, roughly.
It always takes several restarts and various combinations of deleting
tag_cache, etc, before the database finally magically appears, and I
have no real idea of what I did which finally made it happen. I wish
to hell that mpd --create-db had not gone away; it always seemed to work.
