You have EHCI as module, is it loaded?

Same for me from 3.10.17-gentoo to 3.12.0-gentoo. lsusb did show the hubs, but not the plugged-in devices. I tried unloading and loading ehci_hcd, ehci_pci, ohci_hcd, uhci_hcd and xhci_hcd.

My USB controllers are AMD SB850 and "NEC Corporation uPD720200 USB 3.0 Host Controller".

I also did the .config-diff. The only obvious thing are the lines
CONFIG_USB_ARCH_HAS_OHCI=y
CONFIG_USB_ARCH_HAS_EHCI=y
CONFIG_USB_ARCH_HAS_XHCI=y
which are missing from the new .config, and which are "no" in a menuconfig search. These options have no prompt.
Edit: sorry, this information was already in the OP.

Edit 2: The comment in the section of drivers/usb/Kconfig which defines these options says: "These are unused now, remove them once they are no longer selected"

emc,

Mice and Keyboards are USB1.1 Low speed devices.
On some USB hardware you can use ehci-hcd with transaction translation enabled. Thats off in both of your kernels, so while its interesting its not your issue.
The USB1 driver always works. Thats ohci-hcd as long as your USB chipset is not Intel or VIA.

Some keyboards and mice need extra drivers.

What does lspci say about your USB root hubs?
What does lsusb say about your mice and keyboards?

I can see OHCI is loaded:

emc,

It isn't working as tho OHCI driver has not picked up your USB1 hardware.

Some hardware is fussy about the module load ordep

OK I will recompile kernel I let you know.

I know is different topic, but maybe you know I have problem with mouse when laptop is on battery my mouse is turn off when is not use in 2-3 sec. (plug out/in fix problem) After emerging powertop it was advised to enable USB_POWER_SAVE something in kernel. Anyway it was warning in menuconfig that some mouse can't be enabled after turn power off for USB port. Can I keep kernel option only for some USB port?

emc,

Powersave is an all or nothing thing.

Do some battery life tests with and without powersave for your use case.
Maybe the battery life is very little different?
