Lilli and Mb408 are two Italian braille display of 40 cells. Lilli is connected via usb and Mb408 has two models, one connected in serial mode and the other with bluetooth too.
I tested directly this two drivers.

Just to update you on this, we have no problem with including the Python drivers in NVDA. However, I'm still uncertain as to whether we want to start including dlls like this into misc-deps. While they're not too large, the more we include, the bigger things will get. Mick and I will need to discuss this at more length. Perhaps the optional components proposal is the best solution for this, although I'm still not sure about this.

I suspect that the USB display requires drivers to be installed on the system. When the drivers are installed, is the required dll also installed? This would make more sense than multiple products carrying around their own copy of the dll. If not, we should at least request that the manufacturer do this. I'd rather not include dlls for hardware which isn't portable and requires software installation anyway.

The bluetooth and serial displays may be another matter, as they possibly don't require software to be installed on the system, which makes them essentially portable. Is this correct?

No response from the contributor, so this won't make it into 2009.1.

Replying to jteh:

I can confirm that both drivers do not need components already installed. The included dlls are completely portable. The only issue to solve is related to the port and baurdrate choices. At this moment serial port is setted to com1 and baudrate to 19200. Thanks you

(In #426) Note that this won't work for BRLTTY, which is what is used to support all serial displays at present, as all display configuration has to be done using the BRLTTY configuration. It will only be useful for native NVDA drivers such as the MB408 driver proposed in #241.

So I assume the Lilli must use the USB HID protocol in order to function under Windows without a driver? If you plug this display into a computer which it has never been installed on before, will it just work without needing driver installation? That is, does Windows have drivers for it by default?

The MB408 driver probably requires #426 (dialog to set serial port) to be useful, so it will need to wait until that is done.

Bah, silly Trac.

why silly ticket?
I see Alva dll is shipped with NVDA, so I don't understand the problem to include at least the lilli driver.

Comment 9 by jteh on 2010-03-01 20:12
I've already explained the difference. To summarise, the Alva BC640 does not require any drivers to be installed on the system, so the dll must be shipped with NVDA and it is then useable portably. If the Lilli does not use HID, it is not possible for it to be completely portable and it requires drivers, so the dll should be shipped with the drivers instead. This is why I keep asking whether it uses USB HI`D.

I don't see any difference in fact.
When you attach Lilli for the first time, Windows sees it as a standard generic device.
You don't install any driver, Lilli needs only the dll and the .py driver in order to work properly.
If you don't believe me, I can show this ticket to the engeneers that make and work to this display braille, since we are in strict contact.

So I assume it appears as a USB HID (human interface device), as that is the only way to have Windows automatically install drivers. If this is the case (and this is what I've been trying to get a straight answer to for a while now), then we can certainly include the driver for Lilli.

Have you tested this NVDA driver? Does it still work?

Yes, Lilli drivers works without any problem with NVDA.

Lilli driver added in eb64a07. It'd be great if someone can confirm that this works, as I made a couple of very minor changes.

The MB408 driver is going to have to wait until #426 is implemented.

Hello James,
Lilli drivers work very well without any problem.
Tested with snapshot 3638.
Thank you.

Even if #426 gets implemented in 2011.1, the MB408 driver needs to be updated for the new input framework. The Lilli driver needs updating as well, but it's already included and will still work.

New driver for Lilli.
The dll has been updated in order to solve some USB connection issues.
the .py file now contain following gestures:
"braille_routeTo": route
"braille_scrollBack": LF
"braille_previousLine": UP
"braille_nextLine": DN
"braille_scrollForward": RG
"kb:shift+tab": SLF
"kb:tab": SRG
"kb:alt+tab": SDN
"kb:alt+shift+tab": SUP

I know it is quite impossible to put this changes in NVDA user guide for 2011.1, but if you can put the driver it will be good for italian users.
The driver has been tested before committing it.

Thanks for the new driver. Unfortunately, it cannot be added to 2011.1. It will be considered for 2011.2.

MB408 should be addressed separately and is extremely low priority as per #426. I still need to commit the updated Lilli driver.
Changes:
Changed title from "drivers for Lilli and Mb408: two Italian display braille from MDV" to "driver for MDV Lilli"
Milestone changed from near-term to 2011.3

Comment 19 by drein on 2011-07-08 08:27
Can you commit the lilli driver for 2011.2 please?
It is here for a long time, and we must say every user to download NVDA and update the driver manually.
It has not sense for me...
