>Err, precedence, really? Won't that let brltty still start?
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.
