Along with Intel USB 3.0 Host Controller drivers, a utility called "iusb3mon.exe" (Intel USB 3.0 Monitor) was installed at startup.

What is its role in the system? What purpose does it serve? What does it do, so that Intel has elected to add it to my Startup?

Or to phrase it differently - If I choose to stop the iusb3mon.exe process, what USB 3.0 functionality will it disable? As far as I can tell, everything works just fine without it, so I'm wondering what's missing.

It's for monitoring/managing the USB3 ports. What exactly do you want to know? What problem are you facing? –  Ƭᴇcʜιᴇ007 Mar 2 '13 at 15:29

@techie007 I'm facing the problem that I have a process in my system whose purpose is unclear. USB ports are "managed" within the kernel, with a kernel mode driver (in Intel's case, iusb3xhc.sys). Microsoft EHCI driver (usbehci.sys) does not come with a "whatevermon.exe" utility. If I stop iusb3mon.exe, I can still connect USB 3.0 devices just fine. To phrase it differently - what am I missing by not running iusb3mon? –  Ilya Mar 4 '13 at 14:42
    
@techie007 - I don't think the OP has a problem, I think he/she just wanted to know what does it do! And you've answered it! :) –  Dave Mar 4 '13 at 16:29

He did not answer. I could discern myself that "mon" stands for "monitor". I want to know what's there to "monitor". –  Ilya Mar 5 '13 at 14:30

@techie007 I'm sure you guys have a lot of n00b problems here, so I understand your initial response. However, when it comes to "What does this process actually do questions" the internet is full of absolute auto-generated garbage. It would be nice if SuperUser could step-up to the plate here and try to be a definitive resource for common processes / drivers. I cam here for the same reason. "Do I actually need this, yet another process running?" –  Jonathon Reinhart Nov 6 '13 at 9:20

It's a program that manages your usb 3.0 powered connections. Basically it's there to see when powered devices are plugged into your usb 3.0 ports. It's part of what makes your usb 3.0 ports work well so it's best not to mess with it. ''Source

As far as I can tell, I can still connect USB 3.0 and other devices just fine when this process does not run. Furthermore, the linked resource provides very poor, mostly autogenerated information about this process. –  Ilya Mar 4 '13 at 14:45
    
Fair enough about the link, but I'm still certain that it is a program that manages the higher functions of usb 3.0, without it I assume that it will still run as 2.0 –  Shay Hamblin Mar 5 '13 at 1:32

What kind of "higher functions"? –  Ilya Mar 5 '13 at 14:29
