This problem has just been fixed (thanks to you having reported it) in the 
latest development code. One option, therefore, is for you to build and use the 
latest development code. You do have another, probably simpler, option, though. 
It's to explicitly specify the braille driver and braille device within your 
/etc/brltty.conf file.

If you're absolutely sure that you'll only ever have one USB serial device then 
you can always assume the ttyUSB0 device name. If you ever have more than one 
of them, though, then you won't know for sure which number will be assigned to 
your braille device. If you're willing to assume ttyUSB0 then these lines 
should work:

   braille-driver bn
   braille-device serial:ttyUSB0

If you'd like to be more explicit then give these lines a try instead:

   braille-driver bn
   braille-device usb:vendor=0x1c71+product=0xc004
