Question Upgraded to Link - Repeatably lose H80iGT Cooler Instrumentation Data

Windows 7 Pro x64
Corsair H80iGT Cooler
Corsair HX850i Power Supply
Corsair Link
Corsair USBXp Driver - (Date: 7/4/2010)
Motherboard: Asus X99-A Revision: 1.xx (AMI BIOS: 2101)
CPU: Intel i-5820k CPU

Upgraded to Link - Repeatably and consistently eventually soon lose H80iGT Cooler Instrumentation Data to Link - No errors in Device Manager for H80iGT Cooler driver

I can rely on that within a day or three that I will lose communication/connectivity from Link to/from my H80iGT cooler. This has happened back through many versions of Link, and has just been something I have rebooted system each time for a couple of years. And other times, to get a temporary resolution without having to reboot every time to fix, I would just uninstall (not checking the box "Remove Driver") the Corsair H80iGT USB driver from "Device Manager" under "Universal Serial Bus Controllers", and get temporary restoration of communication.

But I noticed at the last upgrade of Link 4.8 the USB driver had changed from an Asetek OEM driver with the descriptive name of "Corsair Hydro Series 7289 USB" to now "Corsair USBXp Driver" with Corsair as the driver manufacture and a version of So I thought maybe my long-standing issues of losing the connectivity between Link and the H80iGT would be over. Well, no such luck. The newly installed USB driver seems to be an older date than the Asetek driver of before.

If it doesn't just stop working on it's own after a few days since last boot, I can also plug in a standard USB device to any USB port and it might stop the communication between Link and the H80iGT cooler. No errors indicated anywhere though.

I am a 28 year IT Senior Network and PC administrator, and so I can tell you that my system is very healthy. No dings in Device Manager. All drivers and current and system is up to date. No issues with system whatsoever besides this annoying need to reboot or un-install and re-install USB driver for H80iGT.

Is there any solution other than what I've already tried of removing and re-installing Link to keep this USB communication working for longer than 3 or so days?

Default Second installing

I gave up trying to get the latest CL software to work properly and reverted to Things are stable now.

Corsair software development is incompetent, mediocre and probably does no regression testing. This is their software working with their own hardware and they can't get it right. Who has time to spend it in forums?

Default has already shown me much better stability in just the two days I've been using it.
Thank you.
