QHY driver timing out during raw photo transfer using gphoto driver #42821
Hello there,

When using both QHY and gphotos driver at the same time, it seems that the QHY driver times out and lead to a crash in PHD2. The QHY driver works fine for hours straight when I'm controlling the camera with a remote control. As soon as I try to use the gphotos driver to control my Pentax DSLR, PHD2 guidescope preview freezes while Ekos is transferring raw files from the DSLR to the Rpi. At some point, PHD2 complains about QHY driver timing out, and I usually need to restart guiding.

Could it be a power issue (I don't use a powered hub at the moment) ? A USB bottleneck somehow ?
I'm not asking for a solution directly (because miracles are rare :D), but I don't really know where to begin with :(. I'm new with INDI and don't really what I could try to do to diagnose my issue.

Regards,
Bertrand

PHD will make several attempts to re-connect the camera.
