For those who are following this "port" to Windows WSL, here is the latest update:
ZWO ASI178 guiding camera already available under Windows WSL.
EQMod mount already available under Windows WSL.
ASI533 camera now connected & tested under Windows WSL:
Esatto focuser now connected & tested under Windows WSL:
Following on from the previously added & tested USB devices, both recent added devices did not cause any issue. So I am convinced that other USB devices not tested in this setup also will work without any problem.
Under the condition it is "open" this night, a real test is planned.
