[BRLTTY] BrailleSense QWERTY

[Vincent LE GOFF]

Hi,

I'm afraid I can't help much.  I'm running Vinux verison 5 (I didn't 
mean to take much risks with accessibility for this first try).  But I 
run a VritualBox.  The host system is still Windows.  I had to install a 
driver on Windows to help the device be identified, but Windows doesn't 
know what it is (hopefully NVDA can interact with it anyway).  When 
switching to my VM the USB port is transfered directly to Ubuntu, but I 
didn't experience problems.  Due to the time it takes to emulate the USB 
port, I don't have Braille on my logon-screen.  But if I unplug/replug 
the BrailleSense, BRLTTY is here in seconds, telling me that this screen 
isn't a text window (which is true).  I didn't have anything to do to 
help BRLTTY recognize it, just explaining VirtualBox to transfer this 
USB port whenever I launched the VM, which was hard enough :D .

Hope that helps a little,

Vincent
