USB 3 Controller Resource Exceeded error

Product Name: EliteOne 705
Operating System: Microsoft Windows 8.1 (64-bit)

On  power up,  The following error message is displayed:

 

" USB Controller Resource Exceeded, The Controller Does not have enough resources for this device"

 

The USB 3 port is connected to an external 7 port USB 2 hub.  Connected to this  7 port hub are a variety of devices. The two of interest are 2 cameras "Videology 60V002-C" . The application I have will only display one camera at a time. Normally both camera are displayed simeltaneously

 

Everything works fine as long as I plug the the hub into the  USB 2 port. Unfortunately, HP is obsoleting USB 2 in favor of USB 3

 

The system has a AMD 3.0 eXtensible Host Controller along with a USB Root Hub xHCI

 

I've tried the newer computers with the USB 2 - USB 3 pass-thur with no luck.

 

I also tried diabling unused USB controller/root hub in both the BIOS and Device Manager and switching from the rear to side USB 3 ports, updating drivers,  converting to a external USB 3 hub, all with no luck

 

 

Any help greatly appericated

Re: USB 3 Controller Resource Exceeded error

I am facing a similar problem with an HP EliteBook 8570p laptop.

"Not enough USB resources"

On my previous EliteBook 8740w, I could connect 15 USB devices without problem. Now, on the EliteBook 8570p, I can only connect 7 devices!

Is this a limitation inherent to the 8570p? and is there a workaround to get more USB devices connected?
