I am using
- a Canon EOS 600D (Rebel T3i) or newly a ZWO ASI294MC Pro (USB3),
- Starlight Xpress Lodestar X2 guiding camera,
- Seletek Armadillo2 focuser control and
- an Digitus USB to Serial converter (FTDI / FT232RL chipset) for the mount.
This equipment is connected to a USB-Hub EXSYS EX-1183HMVS, 4 Port USB 3 Hub. This hub has a metal housing. It uses a Genesys chipset. It is not possible to change the address or IRQ settings manually, they will be obtained automatically by the system (BIOS) and operating system. Via external power supply it is possible to provide a maximum of 1.5 A on each USB port. It is additionally equipped with a USB peak power surge protection. Connectors: 4x A-Port, 1x B-Port, 1x T-Block 7 - 24 V, 1x 12 V Connector (5.5 mm / 2.1 mm). There are similar hubs with a greater number of ports.
The hub is connected to a Fujitsu Lifebook E746 FHD via a USB3 connection (cable length: 3 m).
This configuration works absolutely reliably. I have not experienced any issues with USB transfers.
I don’t know which frame rates can be realized with the ASI since I don’t image planets or the moon, so frame rate isn’t a subject for me.
