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
in reply to Florian

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
in reply to NV Access

@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 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.
in reply to NV Access

@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 ahh, forgot to include you. Basically just tried hwio log, none of the keys register at all
in reply to Florian

@twynn Thanks heaps! I've asked someone else to have a look later today and we'll see if he can shed any more light on it.
in reply to Timothy Wynn

@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
in reply to Florian

@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" nvaccess.org/files/nvda/docume…

@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 :)
in reply to Florian

@NVAccess Hmm. The release notes has two possibly relevant entries under the "Other Fixes and Improvements" heading of their release notes:
* Apple TV Support: Added compatibility.
* Braille HID Ready: Supporting the upcoming release of Android Braille HID

@twynn 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?
in reply to NV Access

@NVAccess yeah it's quite new. I have another person with me here who saw the exact same thing happen, so I doubt restarting will do much but will try.
I'll see if I can get a HWIO log at least. The display used according to the Settings dialog is currently "Standard HID Display", I forget if it was more specific before. let me look at logs...
in reply to NV Access

@NVAccess Ok so I can be brief re: the log: alog set to input/output and with the HWIO category enabled shows absolutely nothing when these keys are pressed. I see laptop keyboard gestures, and I see the braille dots being rendered, but the keys on the braille display register nothing at all
in reply to NV Access

@NVAccess For me it works to some extend. I use bluetooth most of the time and haven’t tested the USB connection yet. Before I installed the new update for the Mantis, most of the time NVDA would connect to the Mantis as a Humanware device, sometimes also as a HID device, but for me it worked better when the display was recognised as a Humanware Brailliant device.
