Hi there!
I just built a brand new PC yesterday from the ground up - all new parts. The hardware profile is in my user profile, but I'll specify my Corsair RGB below.
6 LL-series fans all connected through their fan controller for RGB (then the Commander Pro channel 1) and through the Commander Pro for fan control.
4 Corsair RGB strips on Commander Pro channel 2 with a single extension cable.
2 Corsair PC3200 RGB DIMM in channel 2 and 4 on my Asus Maximus X Code
1 Corsair Hydro H150i Pump (uses 3 of the above LL fans for RAD cooling instead of the stock fans)
Corsair Link updated to the latest version (4.9.7.35)
I've been having troubles controlling the Hydro pump, and it's been inconsistent. For starters I will say I've tried both iCue and Corsair Link 3 times each (with a complete uninstall/reinstall for each one each time). All of the above devices I've mentioned show up successfully in both programs except for the pump.
I'm leaning toward wanting to use Corsair Link for now if I can get it to work because I like the UI more and because iCue made my LL fans start going crazy this morning without changing any settings (colors and speed were all over the place and they were flickering). That's besides the point.
What I've tried so far is switching which of the two Commander Pro USB headers I connect the pump to. That actually fixed it (temporarily) and I saw the Hydro in Link. Then I went to finally do the cable management on this new system and in doing so, even though I connected everything the same way, I lost the Hydro again.
It seems to be cooling correct and lighting up (default) correctly. So this issue seems localized to the USB portion of it for detection/control.
I've seen mention of issues with enabling Corsair USBXp Driver in Device Manager for some people, but I don't even SEE this driver in my Device Manager. I've also seen mention of other monitoring software causing issues but I don't have anything installed on this system besides Office and a bunch of games (remember it's all new).
I've updated all of my drivers, including the motherboard and BIOS, to their latest versions. Still no 150i control.
Please help.
