Hi,

I use eurobraille driver, updated from 4.1 because with 3.10 it didn't
work with old eurobraille displays (Clio). So far my logs were 
full of messages such as:
brltty[1618]: input byte missing at offset 2 brltty[1618]: input byte
missing at offset 1 brltty[1618]: input byte missing at offset 1 
brltty[1618]: input byte missing at offset 2 brltty[1618]: input byte

offset 8 brltty[1618]: input byte missing at offset 1 brltty[1618]:
input byte missing at offset 1 brltty[1618]: input byte missing at 
offset 8

But now I installed backported release instead of source (to easy the
next dist-upgrades), now I installed console-setup and kbd to 
deal with iso-8859-15 properly on every tty, these messages appear on
the standard output at every key I do (letter or function) on my 
dipplay. Even if I do with ordinary keyboard I have such result. Screen
isn't readable anymore.

I precise that this bug only appears on a 32bits system, on amd64 only
messages appear in log (it's a problem, but less critical).

Thanks,

Regards,
