Hi Sam, I just received both of my ASI120MC.
AMCap gives me error: ERROR during capture, error code=0x80040209
SharpCAP gives me error: Error during preview (0x80040209)
I am running Windows 8.
Installed the latest iriver 2.0.0.909.
Tried both USB ports.
The camera ZWO ASI120MC camera is listed in the device manager with a warning (exclamation).
Tried both cameras.
Same problem, need help to resolve the issue!
Thanks
