[BRLTTY] [PATCH] don't steal abused USB ids

[Stanislav Brabec]

Several Braille devices abuse USB ids of UART Bridges. As a result,
these devices cannot be automatically detected by USB id. Adding these
USB ids to brltty udev rules breaks wide scale of other USB devices
(USB-serial converters, GPSes, AVR ISP programmers, Arduino devices).

brltty cannot steal these USB ids. If the manufacturers fills at least
textual id of their devices, udev rules can use this for discrimination.
If not, such devices cannot be auto detected. (Or they can be detected
by an unsafe serial communication based helper.)

For now, let's comment abused USB devices out.
