[lug] RHEL6 USB and network issue

[Maxwell Spangler]

On this motherboard, the AMD SB950 chip provides USB 2.0/1.1 ports and
two separate Etron EJ168 chips provide USB3.0/2.0 ports.

Your problem could be the RHEL 6 kernel's drivers putting the AMD USB2
ports into suspend mode.  It's probably not doing so on the Etron ports
which makes the Etron ports work while the AMD ports don't.  If you boot
into BIOS and the USB2 ports that further suggests the hardware works
but that it's the kernel driver that is the source of your problems.

If you execute this

# while :; do lsusb -v > /dev/null; done

Do the USB2 keyboard and mouse peripherals work properly?

What does

# cat /sys/module/usbcore/parameters/autosuspend

return?

If the loop above resolves your problem, boot with a kernel or module
option to disable the usbcore autosupend function and things should work
better. 

If not, tell us more.

Cheers,
