[BRLTTY] [workaround] brltty crashing on windows with NVDA

2017-04-06 Thread Samuel Thibault

Hello,

It seems to be related with the auto-release of the device.  If you
don't use another screen reader with its own driver, you can modify
c:\Program Files\BRLTTY\etc\brltty.conf to work around the issue: in
that file, you can either

- find the line containing 

#release-device off

and remove the # sign there

- or just put

release-device off

at the end of the file.

The source seems to be downloadable on

https://3rdpartysource.microsoft.com/download/Redistributed%20OSS/5.4/brltty-5.4.zip

It seems to correspond to git 8d46edbf16 + a cherry-pick of 738c1d8b76
(which was submitted by microsoft at the time).

I have no experience with it, but, from what I hear, it's more or less a Ubuntu 
system.

>so are it possible to compile?

You should be able to because our Android builds are done on Linux. You'll need 
to install Google's Android SDK (software development environment) and NDK 
(native development environment). The file README.Android contains a section on 
how to do it.

Re: [BRLTTY] Testing on Windows

2017-04-06 Thread Felix Grützmacher - Help Tech Elektronik GmbH

Hello,
the problem occurred in both. I'm trying to find out if Microsoft may have
patched the version of BRLTTY that's downloaded automatically when they
install Braille support.
I'll also find out if it's just the machine I'm testing on that causes the
issue.
Kind regards,
Felix Grützmacher

Which version doesn't work for you? The one I recently built for you to test
with? What about our official 5.4 release?

Good to know!

Thanks.

I hear the Narrator add-on identifies itself as 5.4M.  That raises a few
questions.  If anyone can figure out the URL of the actual
download, that would be highly appreciated for analysis.

I am confused, esp. since I just learnt that I know someone who is successfully 
running an AB4 with BRLTTY and Narrator (one of your resellers, actually, I 
guess you know whom I'm talking about).

So while the error above is another riddle, I too now think that you are 
testing with a device which is different from what we originally had to 
implement support for.  Or your libusb is corrupting packets.  Or
something similarily strange.   To repeat, I know an AB4 user who is
successfully using it on Windows with the BRLTTY version that is being offered 
by Microsoft for download.  So, back to the drawing table:
It would be very nice to know if your AB4 works on Linux.

Hello Mario,
currently installing that exact version from Microsoft as we speak, and then 
we'll test with AB4 and EBR.
If this works for us as well then we know that your driver is working on 
Windows under the right conditions, and that MS figured out those conditions. 
This is great news! Thanks for sharing!

I am confused, esp. since I just learnt that I know someone who is successfully 
running an AB4 with BRLTTY and Narrator (one of your resellers, actually, I 
guess you know whom I'm talking about).

So while the error above is another riddle, I too now think that you are 
testing with a device which is different from what we originally had to 
implement support for.  Or your libusb is corrupting packets.  Or
something similarily strange.   To repeat, I know an AB4 user who is
successfully using it on Windows with the BRLTTY version that is being offered 
by Microsoft for download.  So, back to the drawing table:
It would be very nice to know if your AB4 works on Linux.

Re: [BRLTTY] Testing on Windows

Hello,
you are right in assuming the USB architecture differs between Easy Braille and 
Active Braille. The reason is that Easy Braille has just one relevant endpoint 
for HID communication for Braille input and output, whereas AB4 and AS4 have 
keyboard input as well. So those have the Braille HID endpoint plus the HID 
keyboard endpoint.
I just tested Easy Braille (ID 0x44) with the following result:

Basically the exact same log was already submitted by you in July 2016.
Dave analyzed it quite in detail in 
<20160712095617.gp26...@beta.private.mielke.cc>.

Reading the thread from back then (which unfortunately didn't come to a 
conclusion), I have the feeling the bug is in libusb-1.0, or at least, in how 
we use it.  Having written the support for AB4, I definitely know it worked on 
Linux, I just don't have any right now to test it.
However, I know my AS4 is working on Linux via USB.

> 2017-04-05@09:05:11.514 usbSubmitRequest error 40: Function not implemented.

I don't particularily remember ever having seen this message on Linux.
While I understand from reading the reply linked above that this is just a 
warning, I still wonder if this might be the crucial difference.
AIUI, Dave is saying this warning would force the core to communicate 
differently with the device, maybe something it doesn't do on Linux?

We basically have two different types of Handy Tech USB HID implementations in 
the driver.
The first generation (usbOperations2) was when the Easy Braille was released.
In that version, we are reading/writing from/to the device via HID reports 
(usbHidGetReport()/usbHidSetReport()).  Later on, somehwere around the Active 
Braille, this didn't work anymore.
We had to change to reading/writing HID frames from/to the USB endpoint 
directly.
Without ever having tried so, I have a feeling maybe these two different 
implementations aren't really necessary, and we should be able to impl
