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
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
