Hi There... :| :?
i am using this V3 OpenBCI 32 bit board 8 channels with OpenViBE 1.2.2 which is stable now with the board. but the acquisition server isn't recognizing the board and gives 0 Host Connected. I've done the FTD driver settings described here and on openBCI page but the problem remains the same. I would like to request help on the matter Please.

Hi, everyone ...

I am using this OpenBCI 32 bit Cyton board 8 channels with OpenViBE 1.3 which is stable now with the board. but the acquisition server isn't recognizing the board and gives 0 Host Connected. I've done the FTD driver settings described here and on the openBCI page but the problem remains the same.
we did all the process described in the documentation of openbci and openvibe

Following are the errors I receive during acquisition phase...

Seems some users have got the Cyton to work, its mentioned e.g. here,

viewtopic.php?f=13&t=9729&p=15044#p15005

Please see also this suggestion from soultranscender (thanks a lot!),

viewtopic.php?f=5&t=9731#p15035

ps. merged post with a similar topic.

Cheers,
Jussi

hello jussi

We have tried your suggestion but still problem persists.

We have tried in different system as well as in different version of windows but error is same everywhere.

I think we are neglecting an important point which is not discussed in openbci forum as well as in openvibe forum.

I think it'd be a good idea to take the subject up on the OpenBCI forum as well if you haven't done that already; here we know openvibe, but openbci hardware and the driver is probably much better known to the openbci community.


My three cents,
Jussi
