QHY5L-II Mono maximum exposure

I am running Kstars/Ekos on a RPi3 with a QHY5L-II M as an all-sky camera. It works great except I can't take exposures longer than 19 seconds without the download hanging. If I try to take a 20 second exposure in either preview or as a series in the sequence queue, the exposure timer counts down and then nothing happens. The image doesn't download and the camera becomes unresponsive requiring a restart of the indi_qhy process.

I found this post where Jasem says he can take 30s exposures so its not the driver. Are there USB speed and traffic settings that need tweaking? Perhaps the USB cable is the issue? I will give that a go later.

Thanks!

It turns out that exposures that are multiples of 10 cause the download to hang. I tried exposures of 19, 21, 25, 29, 31, 299 seconds and all downloaded fine. When I tried exposures of 20, 30, 50, 300 seconds it hung and I had to kill the indi_qhy process.
