adding USB Hid support to BAUM braille displays Vario 340 and SuperVario2

[pavel46]

on a SightCity exebision in Frankfurt Germany BAUM introduced a new 40 cells braille display Vario 340. this new braille display is supporting only USB HID connection. additionally, Baum has also another braille display model SuperVario 2. this braille display is supporting USB cirial port connection, bluetooth and USB HID connection. currently existing driver for the BAUM braille displays is not supporting Vario 340. it is supporting SuperVario 2 Vi USB cirial port and via bluetooth, but it doesn't support this display via USB HID. so i'm asking to add support for the USB HID connection for Vario 340 and for SuperVario 2.
for SuperVario 2 and humanware brilliant models produced by BAUM i found following USB HID idis:
6001 hex
SuperVario2 40

6002 hex
SuperVario2 24

6003 hex
SuperVario2 32

6004 hex
SuperVario2 64

6005 hex
SuperVario2 80

6006 hex
Brailliant2 40

6007 hex
Brailliant2 24

6008 hex
Brailliant2 32

6009 hex
Brailliant2 64

600A hex
Brailliant2 80
for Vario 340 i found following USB HID idies:
Vario340 ="0x6201"

6010 hex

Thanks for the info. A few questions:

1. Looking at BRLTTY, it seems the vendor id is 0x0904 as with most other Baum displays. However, I'm unclear about the vendor id for the Vario 340. You wrote two numbers: 0x6201 and 0x6010. 0x6010 looks like it's probably the product id (and I'm guessing the vendor id is 0x0904, but what's 0x6201?
2. HumanWare now produce their own Brailliant B displays. My understanding was that Baum were no longer producing Brailliant displays. So what's the story with the Brailliant2?
3. Is Bluetooth auto detection working correctly for the SuperVario2? Do we need to add additional Bluetooth names for it?
4. Is Bluetooth auto detection working for the Brailliant2? Do we need to add additional Bluetooth names for it?

Another question: you mentioned that the SuperVario2 supports USB serial. Do you mean you can switch it to USB serial mode instead of HID? If so, does auto detection work or do you need to select the serial port manually in NVDA? if auto detection doesn't work, is the USB product id the same when using USB serial mode? (Often, the product id is different between these two modes.)

Hi Jamie.

Regarding the questions in your first mail my colleague provides following infrhmation:

1.   The vendor ID of the Vario 340 is 0x0904, like all current BAUM USB products. 0x6201 is the product ID of Vario 340. 
   

2.   The Brailliant2 is a customized SuperVario2, like the “Brailliant” is based on “SuperVario”. I do not know if or how many of them are sold to HumanWare. Of course, they have now the Brailliant B. I was not able to get the information how many of them are delivered to HumanWare, but surely it is just a handful. 
   

3.   The BlueTooth-Name of “SuperVario2” is the same than the current response of “SuperVario”. So a BT AutoDetection that works with a “SuperVario” with actual firmware should work also with a “SuperVario2”.
   

4.   The same like above, autodetect should just work.
   

Regarding the question in your second email , yes I have to go into the advanced menu of the braille display and select USB instead USB HID chennal. The autoditaction usually works well.

With kind regards.

Pavel.

Thanks! So what is 0x6010 with regard to the Vario 340?

[pavel46]

Hi Jamie. May be it was written by mistake there. The id of Vario 340 should be 6201.

Best regards.

Pavel.

Here is a try build with support for these displays. Please test it with as many of these displays as you can.

Hi Jamie.

Thank you very much for this new build.

My colleague tested this trial build with Vario 340 and SuperVario2 40 cells braille displays. He reports that both displays are recognized and working properly. Both routing keys and the D keys of the braille displays are supported.

Thank you very much again.

With kind regards.

Pavel.
