[SOLVED] MOBO USB Headers

[lottaphotos4]

HI, just wanted to check on something before I touch my hardware.

I have an ASUS HERO X motherboard with two internal USB headers.
Currently have Corsair H115 CPU cooler using one of them, and the front panel USB 2.0 using the other (two ports into one plug, Phantex Enthoo PRO case, as designed).

I just bought a Corsair Cmmander PRO, which also requires an internal USB port, but offers two USB ports on the device itself.

What I'd like to do is plug the Commander PRO into the internal USB header that the front panel is USB cable is currently using.
Then I would be plugging my Corsair HXI 750 LINK USB cable into the Commander PRO, and the front panel USB cable into the other USB plug on the Commander PRO.

Simple question is wil that work?

My concern is I've seen some comments about the internal USB headers being "dual port" headers, and it's got me trying to do math. Having the two USB ports from the front panel plugged into one of those "dual headers" seems reasonable (two ports into a dual port), but if I instead do as indicated and plug the front panel dual USB connector into the Commander Pro, and the Corsair Link USB into the Commander Pro, and then plug THAT into the motherboard internal USB header, it feels like I'm plugging THREE things into a "dual port".

So the complicated way of asking is "How many USB devices can be plugged into one internal USB header and have all three properly recognized?" I'm not going crazy with a bunch of device USBs, just the three (PSU, front panel USB, Commander Pro. I've heard that one header can correctly handle more than that (e.g. if I were to go get an NZXT internal USB extender and plug THAT into the internal USB header), so I [think] what I'm doing should work.....but I'd kinda like a bit of YES or NO before I start pulling wires, etc.

Thnak you for you tolerance of a possibly silly question.

Be great if somebody has done similar and can confirm it will work.

(I know I could plug the Corsair H115 USB into the Commander Pro. Was tempted to do that, but heard a couple things about the H115 not being properly rexognized in that configuration, and if there's going to be any kind of issue, I'd prefer it was with a USB connection, and not the thing keeping my i7-8700K happy..)

With an appropriate splitter/adapter, e.g. a USB hub, you can 'share' one port with many devices. It will be sharing the bandwidth...and also the power. The power may be the biggest concern so knowing the draw of each device you have on any one port will be good to know.

An active hub provides supplemental power to each USB socket (port) and provides some degree of signal conditioning to deal with the inevitable degradation that occurs. A passive hub/splitter will be similar to what you want to do and effectively wires multiple sockets to one plug; they are usually going to limit you to USB 1.0 bandwidth shared between all output ports.

If you're committed to this plan you could simply try it and see how it works out. It doesn't sound like the bandwidth needs of any of the devices will be very much so it should work. Or not: I'm pretty sure that if a port's power draw is exceeded it will simply shut down the port or refuse to work and throw an error code in the event log.
