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

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?
