[BRLTTY] USB problem with BRLTTY, BRLAPI and Orca combination

[Jason White]

I was using Brltty with Brlapi and Orca (actually, Firefox/Iceweasel 3 beta
4), when the braille display disconnected and reconnected with the errors
logged below.

The BRLTTY revision is 3630.

I've had all sorts of hardware issues recently (not involving the braille
display, fortunately). I very much hope this turns out to be software rather
than hardware as I'm hoping that the hardware problems have been solved now. I
still have suspicions about one of the ECC memory modules in this machine, but
I've checked the kernel logs and there haven't been any ECC errors reported
recently.

Here is the log:
