That is the message I've been fighting since I completed this build after upgrading from a Rampage IV-E.
My USB devices are:
Rear Panel:
HooToo USB 3.0 Hub plugged into the first ASMedia 3.0 port
-Netgear USB 3.0 Wifi Adapter
-ASUS USB 3.0 Bluray drive
Monitor USB hub is plugged into the first Intel USB 2.0 port
-Razer Blackwidow
-Razer Naga
-Razer Orbweaver
-Xbox 360 Reciever
Internal Headers:
ROG_EXT USB
- ROG Front Base
USB 2.0 Header
-Corsair Commander Mini - Controls Fans, LEDs, AX860i and H100i
USB 3.0 Header
-Case Front Panel
With all that plugged in I am able to plug one additional USB device into any port. After than any other USB device I plug into any
port, be it front panel on case, Hootoo hub, Intel 3.0 ports(which are completely unoccupied), etc I get a message that pops up saying
"Not enough USB Controller Resources". I've tried multiple combinations of plugging all my devices in other USB slots and the problem
doesn't cease. I've ensured all the drivers are current. This can't be a power issue because most of my devices are on powered hubs.
Is this some sort of limitation with USB 3.0? Faster but less room than 2.0? I ask because on my previous system I never
ran out of resources and kept a 4tb My Book, 2tb Passport, a USB thumb Drive and a printer in addition to what I have listed above.
At one point on the RIV-E system I had 2 HDDS, a thumb drive, a wife adapter, a bluetooth adapter and an iphone plugged into the Hootoo
