Unfortunately, I had only tested Brailliant shortly, and it is not here now.
Of course, I had also executed BRLTTY using Debian's ordinary way "/etc/init.d/brltty start".
I think "/etc/init.d/brltty start" is functioned as an equivalent of "-d usb:".

In spite of "idVendor=1c71, idProduct=c005" is recorded in BRLTTY's Humanware driver source as its id,
Linux kernel recognizes a Brailliant as an USB modem then load cdc_acm.ko module.
I don't know USB device recognition mechanism deeply.
