ASI1600MM-Cool Extremely slow transfer speeds

pipplo

I am having a problem with SGP (ASCOM) but not with Sharpcap.

I setup a sequence to take 100 frames and I got to about frame 62 before things appeared to be stuck on 'Downloading'. However when I looked at the file system I could see the file size growing for the current frame, but very very slowly. It took about 20 minutes for one frame to finish.

I rebooted and the speed looked fine so I started the 100 frames again. Again the same problem occured with very slow download speeds for later images. The first 10-20 which I watched manually worked fine.

I have SGP logs for the issue. Near the end you can see it took 500,000ms for the last frame to complete while all of the previous ones took ~20,000ms: https://drive.google.com/open?id=0B_jRsujhCGrWSXUxV0NWWk0yckk

Is there any ASI/ASCOM logs I can capture to help?

System Config:

SGP version: v2.5.1.17

ASI Ascom Version 1.0.2.23

ASI camera drivers 1.3.12.28

USB Setting: 40

USB 3 & 2

Intel Compute Stick

I did not power or run the cooler for these experiments

I heard somebody say this is a bug of SGP

and newer version of SGP should fix it

I was able to figure out the problem had to do with the microsd card I was using as a destination. See some details here
