Anyone who owns a #mantis Q40 #braille display noticing that thumb and routing keys are no longer passed onto #NVDA after the v2.4 update? Lot of cool stuff, but something seems to have gone screwy #screenReader #blind #humanware

@zersiax I haven't seen any other reports of this yet (I don't have a unit to test with myself) - when did the v2.4 update come out? First, try restarting the PC - sometimes that fixes quirky behaviour. Do let me know if it's still happening

@NVAccess It came out, according to the timestamp Tuesday, 10 December 2024, 21:10:21 GMT. I have not updated but can do so and provide info as needed. Assume hwIo debug logging info would be useful to have?

@twynn @zersiax Thank you, that would be useful (either to us, or to Humanware) - but maybe make sure you've got a copy of the older driver if you need to go back as well.

@NVAccess Oh, uh... they don't let you go back, just like iOS, Android, and practically everything these days which is all sorts of nonsense, but I only have it as a HID-compliant display tangentially for work, and my primary display works without issue even though there's a missing dot. I'll do a before-and-after comparison when i have a chance. @zersiax

@twynn @NVAccess So, over USB, the device still shows up as being a Humanware display and the keys work. On Bluetooth, it's Standard HID braille display and the keys do not work. related, perhaps?

I've emailed Humanware about this,as well

@zersiax @twynn Thanks, this might be getting closer. Looking at our user guide, we just say: "The Brailliant BI and B series of displays from HumanWare, including the BI 14, BI 32, BI 20X, BI 40, BI 40X and B 80, are supported when connected via USB or bluetooth. If connecting via USB with the protocol set to HumanWare, you must first install the USB drivers provided by the manufacturer. USB drivers are not required if the protocol is set to OpenBraille" https://www.nvaccess.org/files/nvda/documentation/userGuide.html#HumanWareBrailliant

@NVAccess @twynn hmm, yeah, there's a "TerminalTools" file on the q40's support page which supposedly installs drivers for JAWS 2018 and up, but JAWS already works here without having this installed, and it's really Bluetooth only where NVDA currently has an issue :)

@zersiax @NVAccess Hmm. The release notes has two possibly relevant entries under the "Other Fixes and Improvements" heading of their release notes:

@twynn @zersiax If it is using HID by default, it may be that it's HID support doesn't include support for the thumb and routing keys? Can you switch to the humanware driver for it perhaps?

@NVAccess @zersiax Hmm. using build 4201, the display shows up as "(Standard HID Braille Display" with Bluetooth, but thumb keys and cursor routing works fine for me with NVDa 2024.4 and Brailliant 2.4.0.build4201. See this pastebin where I have input mode on and pressed all four thumb keys and first and last routing keys:

@NVAccess @zersiax I cannot choose "HumanWare Brailliant BI/B series / BrailleNote Touch" as the display in NVDA while using the Bluetooth connection.

@NVAccess @zersiax My apologies for the garbage data. I have the Brailliant BI 40X not the Mantis Q40, so obviously things would differ. Please disregard everything I said.

Written by Florian on 2024-12-12 at 05:58

@twynn @NVAccess same. Trying to use the humanware option explicitly currently fails. If the q40 can switch braille protocols,I wouldn't know how that could be done

@zersiax @twynn @NVAccess I don’t think there’s a way to switch protocols on the Mantis. I just tested with the latest build, and I can use the display with the standard HID protocol without any issues via Bluetooth. Other drivers don’t work. I’ll keep an eye out for any other users having the same issues, but can’t replicate it yet on my side.
