Pavel created a new topic ' QHY 5L-II low speed on RPI4' in the forum. 5 months ago

Hi

I have a Raspberry Pi 4 and a guide camera QHY 5L-II-M. It is detected perfectly on RPI, but it seems that transfer speed is very low, ~3.5MB/s. This gives downloading delay after exposure ~0.4-0.5s, making use it for guidance questionable. When I connect camera to a big computer, it works just fine (0.07-0.09s downloading time). lsusb -t shows speed 480 Mbps on RPI, so I am out of ideas how to make it works faster.

I would appreciate any help/suggestions/etc.

I am not sure what happened. I sent a post - and it didn't appear neither in My Topics nor in the forum. I read this warning and was waiting for approval. However, it didn't happened, but now I have the right to post (?).

Many Thanks...


to the moment ~36 hours have passed since I tried to post. Could you please give some clues, what does it mean "a few hours" - 100h? 200h?
It's just a joke, but I would appreciate if you verify my post, grant me the right of posting and delete it so I will be able to post it again.
