Did you put brltty-wrapper in /lib/udev or in /usr/lib/udev on this second

[BRLTTY] More Stuff with Udev and Systemd
I transferred the system had built to another computer. This time the
90-brltty.rules
and
brltty-wrapper
worked.
But I saw some weird messages from the kernel. Every other second or so, it
said something like
{ long_dmesg_number usb_fs interface claimed by USBHID while 'brltty' sets
config 1 }
That isn't it exactly, but close. It said something about USB being claimed
while brltty set config 1.
Any idea what that is all about?

Thank you. I've reworked it some (attached as tty-braille-1.patch). Please
verify that I haven't broken it.

I don't think there's a need to make it configurable. We can always add a
parameter for that should it ever be requested.

Here you need to add row*brl->textColumns to col, to get the proper line
from brl->buffer. Apart from that, the patch looks good. An option could
be useful, but it shouldn't be too bad to always print it, on most
systems nowadays it will be fine.

[BRLTTY] Adding a dot display to tt driver
Hi.
I was wondering whether it was possible to add a dot display to the tt
driver. I am aware of the XW driver, but it has more library
dependencies, and in many distributions, you have to configure it to use
an utf8-aware font. However, most terminal emulators have support for utf-8.
I wrote the following proof-of-concept patch for the driver. It just
adds an additional line with braille characters. However, it would
probably be better to make this configurable, and I am not quite sure
how the configuration system works.
Regards, Christoph
