I have indiserver + indi-sx working fine on a Raspberry Pi now - taking images with the setup I uploaded previosuly. It has to be installed from source - the ppa does not seem to have wheezy any more?
The RPi is slow, so a larger timeout has to be set.
I am happy that it works on RPi - but why does it not work in straight Ubuntu? The problem seems related to USB port problems.
Anyway, thanks for the help and the RPi suggestion!
I'm not quite sure which version of SX driver is distributed with Ubuntu. If you can it's always better to checkout most recent source from SVN and build it yourself.
When I plug the camera into a USB port on my big computer (not the little RPi where things work, now), I get this with dmesg:
[25194.576083] usb 2-5: USB disconnect, device number 6
[25201.620053] usb 2-5: new high-speed USB device number 7 using ehci_hcd
[25201.752439] usb 2-5: config 1 has an invalid interface number: 1 but max is 0
[25201.752446] usb 2-5: config 1 has no interface number 0
I am unsure what this "config 1 has an invalid interface number: 1 but max is 0" is about - but I think it is central to the problems I have.
I installed from source both on the RPi and now on the big computer - so I think the problem is not related to indiserver or indi-sx but rather to something about how USB ports are handled by Ubuntu vs the version on RPi. This is probably off-topic for this Forum. Not sure where to go with it: the topic "config 1 has an invalid interface number: 1 but max is 0" is unsolved but common if you Google.
