daytime again, and time to file a bug report, something I've not tried to 
negotiate since my last mind numbing encounter with the dumbest software 
out there, bugzilla.

It, brltty, should not disable /dev/ttyUSB# when its running. Thats what 
gave it away, when I couldn't make heyu run.  The CM-11a is a serial 
device, with a 4 pin telco plug on one end of its cable, and a db-9 for 
a simple serial port on the other, but since the serial port is already 
occupied, a usb to serial adapter is used and that creates 
a /dev/ttyUSBnumber according to how many there might be.

But between the CM-11a complaining that it needed serviced as it had 
stale data (about 2 weeks worth) to report, it hadn't had since wheezy, 
and brltty's erroring on the CM-11a data it sends once a second till it 
gets serviced when it has some status change to report, /dev/ttyUSB0 was 
being destroyed about 1 second after it was created, I assume by the 
CM-11a data being sent to udev as a string of errors instead of being 
given to heyu which has an automatic response to that sort of incoming 
data.

This to me is a bug that needs fixed.  No sense in denying someone using 
braile facilities being denied the use of such adapters.  Thats 
discriminatory.  And its a bug that could potentially generate a 
lawsuit. So I'm going to add the debian-user list to the CC: Maybe 
someone else with more experience at navigating their way thru bugzilla 
can do it based on what I've written here.

Cheers, Gene Heskett
