This is the QHY5, normally it should work after adding the IDs to udev rules. As this device was added to the rules file in SVN: If you use the PPA or my Fedora repo, just wait for the update. Otherwise copy the rules file from SVN sourceforge.net/p/indi/code/HEAD/tree/tr.../libqhy/85-qhy.rules or reinstall libqhy entirely.

If it doesn't work after this it starts to be difficult…

Obviously, Yphrate, we have the same Qhy5.

Could you, if you manage to run your camera, take a picture with a frame (ie not the whole image).

In my case, I observe a freezing of this module. The qhy module is not anymore responsive.

i have find a solution: install ubutu 14.10 + kstars-bleeding and its works
I dont test remote control but in local its good.

Thx all for ur reactivity

Ps@broadcastyourseb: je suis francais aussi :p on pourra s'aider enfin tu pourra m'aider je débute ;)

I will make more test tonight to find what's wrong with my QHY5 and framing.
Maybe I have to open another topic for this issue ?

PS @yphrate je n'ai pas tes coordonnées pour te contacter en MP. Super d'avoir un contact francophone utilisateur d'indi.

Remote control works with a notebook NC10 on lubuntu 14.10, but not with raspberry b+ but i think i have to use a powered hub usb?

next step

@broadcastyourseb: oui c'est cool, je vais avoir besoin de tes lumières pour le focus a base d'arduino

No QHY does not work yet on ARM, waiting for QHY to fix the issue. There quite a few still issues with INDI QHY driver but it is waiting for code changes from QHY itself.
