This is the USB2 version of the 224C. It times-out randomly every few minutes when guiding in astroberry on the pi4 (even with speed=0 and 2x2 binning) - I understand these time-outs are a known issue with the altair driver. However, the real problem for guiding is that it waits 30 secs before timeing out, even with 1 sec exposures. It then starts taking images again. But this gap makes guiding almost impossible. So does anyone know where the time-out length is set, and whether it can be reduced? I can't see any good reason for waiting this long with such short exposures - the download time is negligible.
