Ah, but this is properly emitted in usb-generic.rules, ok.

I'm however wondering about these:

ENV{PRODUCT}=="403/6001/*", ATTR{manufacturer}=="Hedo Reha Technik GmbH", ENV{BRLTTY_BRAILLE_DRIVER}="hd", GOTO="brltty_usb_run"
ENV{PRODUCT}=="403/6001/*", ATTR{manufacturer}=="Tivomatic Oy", ENV{BRLTTY_BRAILLE_DRIVER}="at", GOTO="brltty_usb_run"

They don't seem generic, as they properly match a Braille manufacturer
string?
