I have a similar problem with my QHYIMG-0H camera, it connects successfully but fails when I try to capture a frame:
"[ERROR] GetQHYCCDSingleFrame error (-1) "

These are my first tests with Indi, so I am a bit "lost" and would need some help...

I am using the last stable release of Indi, installed yesterday following the instructions here:

I tried with a powered usb hub, but without differences.
I tried also with Indi installed in Ubuntu, on an other PC, same problem...

I would exclude a problem with the camera, it works well with PHD2 on Windows 7.

I add some logs, I hope they could be useful.
Thanks in advance !
