One thing to note here is that brltty only autodetects USB-connected devices. 
To use the Alva, therefore, you also need to specify -dserial:ttyS0.

You need to use run-brltty if you're running the brltty executable from the 
build tree. If you don't, the newly built executable will pick up the 
(presumably older and perhaps incompatible) installed drivers. This may explain 
the crash when you built 3.9 and tried to use the Alva, i.e. perhaps it tried 
to use the installed 3.8 Alva driver. A check has been introduced recently to 
protect against this kind of problem.

There's no significance other than that /dev/bus/usb/ (actually, udev) 
introduced the no leading zeros format at some point and brltty didn't handle 
it until a recent fix.

If you have the subversion (svn) client it's always helpful, if possible, to 
retest problems against the latest development version. There are notes on 
brltty's download page regarding how to build the latest devbelopment version. 
In this case, however, since using run-brltty did work, you probably then just 
need to do the make install.
