What firmware version are you running on your device? I wonder if something changed in a later version of the Orbit firmware that I don't have. Mine doesn't have an option for RB18 emulation, for example. That said, there are some concerning errors in your log that aren't even related to the Orbit.

Please enable hwIo debugging as explained in this article. Then, restart NVDA and try again with USB HID, no RB18 emulation and provide the resulting log. Thanks.

joshknnd1982 · 2016-10-14T00:51:16Z

I am running firmware version 01.00.56 .

What firmware version are you running on your device? I wonder if
something changed in a later version of the Orbit firmware that I
don't have. Mine doesn't have an option for RB18 emulation, for
example. That said, there are some concerning errors in your log that
aren't even related to the Orbit.

Please enable hwIo debugging as explained in this article
https://github.com/nvaccess/nvda/wiki/DebuggingBrailleDisplayDrivers.
Then, restart NVDA and try again with USB HID, no RB18 emulation and
provide the resulting log. Thanks.

…ms which made some braille display drivers unusable. hwPortUtils.listComPorts: In some rare cases, the SPDRP_FRIENDLYNAME registry property doesn't exist/isn't valid. In these cases, just use the port name as the friendly name. Re #6007.

Thanks. It looks like there is a COM port on your system which is broken and doesn't have a "friendly name". This is breaking NVDA.

Please try this try build. You can just run it as a temporary copy if you like (press Continue running after running and accepting the license). If it doesn't work, please provide another log with hwIo debugging (which is probably still enabled from before unless you disabled it). Thanks.

joshknnd1982 · 2016-10-14T01:51:56Z

is there any way to fix this com port? this is a refurbished laptop.

It's probably just a weird driver or maybe it needs to be reinstalled. Either way, I'm hoping this build will work around it.

joshknnd1982 · 2016-10-14T01:58:02Z

hey i tried the try build and it works. so can you tell me what is wrong
with my comm port and how i can fix it if possible please?

or could you implement this into master as an option for people who may
need it?

It might not be something you can fix; it could be a driver bug. In any case, I do plan to get this into NVDA core. I just wanted to have you verify that it worked first before taking it further, since I can't reproduce it myself.

joshknnd1982 · 2016-10-14T11:26:29Z

yes it works great, thanks! and I installed the try build and updated my
current copy of NVDA to the try build. Hopefully your changes will make
it into the next major NVDA version to come out in a few months or so.
