10 usb ports seem to be quite a few. I would recommend seeing if your motherboard manufacturer has a BIOS update or just unplug the USB device and plugging it into a different port.

Good luck!

I have a Gigabyte Mobo, I have unplugged all devices, updated the Mobo bios and I still get the "Unknow device" with the yellow triangle. Even with all the USB ports cleared I get that error in the Device Manager. We have to keep at it and get a solution.

hey i had the same thing but it was my wireless network that said unknow device go back in to device manager go down to usb controllers and click on every usb root hub and go to properties and look for power managment and untick allow computer to turn this device off to save power this is what was up with mine hope it's same for you to

Keep in mind that front USB ports on many machines are notoriously underpowered...
This unfortunately happens with all manuf.

Well I don't know what to say or believe any more. Right now the "Unknown Device" disappeared again from the device manager and I am not even using the USB port that started it all. I realize that I have 10 available usb ports but I only have 2 printers, 1 web cam a USB wireless keyboard/mouse combo a document scanner and a removeable flash drive and a memory card reader. My Dell monitor (1908fp) has a built-in 4 port usb hub which is also hooked up to the back of the case but I never use it. I keep forgetting it is there. All usb devices. They are never used at the same time except for the Microsoft USB wireless/mouse combo. Everything is hooked up to the rear of the case except when I use the flash drive or memory card reader in the front of the case. How about the next time "Unknown Device" appears in the device manager I uninstall it?? Is it worth a try?? Also my motherboard BIOS driver is up to date

Even if they are not being used, they will suck up energy.

Have you tried disconnecting that monitor hub.
Hubs are known to present problems.

I haven't read through the whole thread, but did you already updated your bios?
It might even be a design flaw or malfunction of the board.

Hard to tell.

I tried to untick the box in power management, the yellow warning is still there.
Windows has stopped this device because it has reported problems. (Code 43)
