BRLTTY only looks for true USB braille displays directly. If you use a USB-to-serial adaptor (of which there are plenty different ones) then it is really a serial braille display to BRLTTY. > The reason why I'd like to use the usb interface > rather than the serial interface is that the braille device is not > guaranteed to show up as ttyUSB0 all the time due to race conditions > and similar issues.

Still, I thought I'd ask first. The udev approach is certainly the sane thing to do in that case.
