I have an Inspiron 580 (end 2010).
I boot my Fedora 19 from Pendrive (USB 3.0) attached at USB 2.0 slot without problems.
Now I have installed a PCI-Express card with 2 slot USB 3.0.
The problem is that at the boot, Bios doesn't find pendrive. No problem when OS is running.
I can not find settings related to USB 3.0 and USB 3.0 device is not among the available boot devices.
What setting should I change and how?
