My ASI-1600MM-Cool camera regularly locks up while downloading an image.
The INDI control panel then shows a yellow expose light and ever changing remaining download times. syslog shows no camera disconnects.
The ASI-1600MM-Cool camera is connected to a 4A powered USB3 HUB which is connected to a USB2 port on a laptop.
It also has a 12V/2A power supply for its cooler but the issue I have is independent of cooler use.
I know the ideal setup is to directly connect to a USB3 port on the computer, but this is not yet available on this system (I may get a USB3 express card).
When connecting the camera to the USB2 port on a laptop all looks fine at first, but on any image download the entire device immediately gets disconnected from the USB bus. I assume this is because of too high power use, hence the powered USB3 HUB. No more USB bus disconnects, but a new problem instead.
I've read advice for the ASCOM world about lowering the transfer speed for USB2 setups. Can this be done with INDI too ? Is it needed ?
I found nothing relevant in driver debug log file, just lines like
DEBUG 1319.690531 sec : StartExposure->setexp : 0.500s
Ubuntu 16.04 , kstars-bleeding 5:16.10+201610151447~ubuntu16.04.1 , indi-asi 0.5+r2651~201610151451~ubuntu16.04.1
Any hints on how to debug this issue ?
