### ASI2600MX This Fix Worked for Me
I've had similar, increasing, problems with image download failures involving a ASI2600MM Pro. Like many others I tried replacing USB cables and power supplies, as well as testing at a range of temperatures to try and isolate the problem. Finally in order to try and determine whether a hardware or 'driver' issue was the cause, I used CCDCiel on Win11, Mac Silicon and Raspberry Pi, running the same device profile on each. The difference being that ASCOM is used on the WinPC and INDI drivers on the Mac and the RPi. The result? The camera functioned flawlessly on both the Mac and RPi, indicating that the problem was not the camera hardware. To cut a lengthy story short, I noted that ASCOM (including the latest release 7.1.3) requires both .NET 3.5 and .NET 4.8 to be present. I found that Microsoft has deprecated 3.5 and this was turned off on both the NUC I use in the observatory and on a desktop in the office, presumably by updates. To reinstate this, go to the Start Menu and then 'Control Panel' on the left hand side, click on 'Turn off-on Windows Features'. This will bring up a dialog box with the .NET 3.5 and .NET 4.8 near the top. Expand the two fields and select all the boxes. My camera is once again working without any problem. I hope this is of help.
Also don't forget to check the USB device drivers under 'Device Manager' to ensure that power down under 'Power Management' has not been turned back on.
Good luck & clear skies!
