Hello,

I'm using a Handy Tech Braille Star 40 connected via usb.
Often, when I press a button on the display, the decided action isn't performed.
However, when I press the button again, the decided action is performed twise.
For example, I can scroll a line up and nothing happends.
When I press the button again, the dispaly scrolls up 2 lines.

This started happening 2 or 3 Jessie-builds ago.
I hope it's fixable.
For referance, the brltty.conf file is included.

Is this happening on a text console or in the X session?

Hello Samuel,

So far, it only seems to happen in the text console.
I just rebooted the actual machine due to upgrade of some packages (including som mate stoff), and now I don’t get braille output in the graphical session at all, except for a line saying “lightdm-gtk-greeter”.
Only speech works.

Regards, Martin

Hello,

Cc-ing the brltty mailing list for more expertise.

It seems there are keypresses issues with a handy tech device:

Would you be able to compile & test git snapshots of brltty so Dave can
iterate with you over the bug?

This is surprising.  Is this happening at the login window, or during
the session, or both?  When that happens, is xbrlapi running?  Which
version of xbrlapi do you have?
