David,
Handy Tech is very responsive and extremely easy to work with. They
have created the Window-Eyes driver. Have you communicated this problem
with them? I have not heard this being a general problem as you are
suggesting.
Window-Eyes simply sends the data to the braille driver. It is up to
the driver to determine it has lost connection and to re-establish
connection with the physical hardware. Imagine if Microsoft Word had to
have code to wake up all the types of printers it supports if they go
into some power down mode. No, this would obviously be a function of
the printer driver provided either by Microsoft or by the printer
manufacturer, not Word itself. If you are not able to directly
communicate with Handy Tech, if you send me very specifically what
happens and such I can forward it directly to them.
Regards,
Doug

Well, may be all correct what you are saying. I have a PowerBraille
here, and it keeps dropping out like described. OK then, that is the
freedom Scientific. Well, the display is old, and likely they ain't
going to update much on it. But what then about my HandyTech display?
Every time I have complained about that one dropping, I am told to go
get the newest driver. Trust me, I have done so, and that has not
fixed anything. In many cases, the drop-out is in the middle of some
activity, and restarting WE and getting back to what you were doing,
is time consuming and frustrating. Does all you state also apply to
HandyTech? In certain cases, I find that the HandyTech display drops
even more frequently than the PowerBraille. And, it is a good deal
newer. Apparently, WE is not just experiencing this kind of behaveal
trouble, only with one manufacturer. So, maybe you should try to get
some kind of a "keep awake" signal sent to the display, every so
often. Or, even a reactivation code of some kind. At least, I find
that I in periodes leave the Braille all alone, since it is not
stabil, and the Braille support in general has several lacks from what
I was used to in other screen readers, prior to switching to WE.

Vaughan,
The biggest issue is Freedom Scientific will not communicate with
us in any way regarding Window-Eyes support for any Freedom
Scientific braille display. Way in the past we had acceptable
communication which allowed us to create a Window-Eyes driver
based on their API. Their API has not changed in years and is our
only interface into Freedom Scientific displays. They will not
communicate with us or update this API in any way. Therefore we
are left with what we have. Typically a braille display
manufacturer will create their own Window-Eyes driver because they
know best how to communicate with it and can keep the driver
updated as new displays and updates are released. There is no fee
involved in creating Window-Eyes braille drivers. Freedom
Scientific has no desire to create Window-Eyes braille drivers.
The issue of the display not coming back after a machine is woken
from a sleep is part of the Freedom Scientific's API driver which
we are using. But for obvious reasons, Freedom Scientific has no
incentive to resolve this for Window-Eyes or any other screen reader.
I am happy to report that most other braille display manufactures
are very willing to work with us and keep their displays
state-of-the-art with Window-Eyes.
Regards,
Doug

I notice this on occasions with other braille displays, but I'm
not certain that it is automatically a Window-eyes fault.
I guess that you are connecting via USB and sometimes a port
power fluctuation, whilst not significant, is enough to shut down
the display. A Window-Eyes restart reinitialises the whole
configuration. the .
Having said this, I believe there are issues between Window-eyes
and the Focus displays, relating to the Freedom Scientific driver
which has to be installed for these displays to operate.
Window-Eyes supports more displays than its main competitor, but
the ability to consistently support each display is severely
hampered as the drivers are third party.
I believe that the Focus displays have huge potential, but for
reasons that only the major players can explain, the interface
with Window-eyes is not great. In fact, I am wondering if I
should replace my Focus Blue with a second Braille Edge.
Others may be more knowledgeable though and maybe more helpful.

I have noticed that, when I wake up my machine after it has gone
to sleep, the braille display will not return and I have to close
and relaunch windoweyes to get it back.
