Hi there,

My Aquastream XT suddenly showed as disconnected in Aquasuite, and when I checked Device Manager in Windows, there was an exclamation mark over the Aquastream device in Human Interface Devices which said it had failed to start, even though the pump was running.

Now that I can assign the Aquastream's Water Temperature reading as a source for controlling curves in Aquasuite 2017, when it failed to start it caused my alarms to go off (because the temps were set to the default 50°C) and thus the fans to be set to 100%. Well, I know that's obvious and unavoidable if the USB device is not detected, but I'm not sure how it failed to start in the first place, and if it cannot be relied upon then what can I do to remedy the situation? Could a bug in Aquasuite 2017 somehow be causing it to disconnect? It's the first time I've noticed it disconnect, but then again before I installed Aquasuite 2017 the pump's Water Temperature reading wasn't controlling anything, so I had no reason to look very often.

Yes, the USB cable is fitted correctly and in the right orientation on both motherboard and Aquastream XT. After rebooting, the device was immediately recognised again.

Unfortunately I don't have another internal USB header free, so I might have to buy an internal USB expansion board or wait until the new year and possibly buy a new Zen motherboard. The header that the pump is connected to only has 4 pins instead of 5, please see this thread: Aquastream XT USB Motherboard Header Connection Question

I was told that it didn't matter and the pump would still work fine, which it does for the most part.

Well, it happened again. I've come armed with a screenshot this time. Haven't changed anything about my config. Most of the time it works, but I'm afraid it's not really reliable enough for me to use as a water temperature sensor, which is a shame because I upgraded the pump to the ultra version for that purpose.



I'm running Microsoft Windows [Version 10.0.14393] with all the latest updates installed, and the latest Aquasuite 2017.

Update: Rather than restart my computer, I tried disabling then re-enabling the USB Input Device in Device Manager. The pump was then successfully detected without having to reset my machine.
