Hi,

I used to have Raspberry Pi 4 and the next list of equipment (all connected through USB):

- Canon 250D
- QHY 5L-II-M
- ZWO EAF
- iOptron mount

All worked just fine. Recently I upgraded Canon EOS 250D against QHY5III715C. Stellarmate recognises it, but then evil "magic" happens:
- when I move ZWO EAF, QHY715 immediately fails to take shots (but after disconnect/connect in INDI panel OK)
- if I try to use QHY 5L-II-M for focusing, this time mount disconnects.
- also were cases when exposition on QHY715C starts, but hangs just before downloading.

I believe it is due to insufficient USB power and I need to buy a powered hub, what do you think? Any other suggestions?

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.
