Sure. It'd only be a problem for that one particular model of braille device. 
In that particular case, users could still manually start brltty, in which case 
it'd still claim the device. That's probably the best we can do for the time 
being because that particular braille device doesn't identify itself very 
uniquely. Even the USB device descriptor strings aren't specific to the device. 
They are:

   Manufacturer: Silicon Labs
   Product: CP2102 USB to UART Bridge Controller 
   SerialNumber: 0001

Perhaps it can be uniquely identified by other USB descriptor data. I could 
analyze that if someone were to send me samples of, say, the 
/proc/bus/usb/devices entries for some of the other devices which use the same 
vendor and product ids.
