I build 3.13-rc6 for exynso-5250. After installing the kernel and
rebooting my machine, everything worked (lpae out of the box, even)
except for usb; I rebuilt the kernel a couple of times, poking at
USB config options, but was completely unable to get USB to work.

Which exynos5250 machine are you trying the kernel ?
I tested linux-next kernel 3.13-rc7 on smdk5250, and on that i could
get USB working (i checked XHCI ports actually,
but i am sure EHCI ports will also work straight away).
Please make sure you are building with exynos_defconfig. And on top of
that i enabled following configs:
CONFIG_USB_ANNOUNCE_NEW_DEVICES
CONFIG_USB_XHCI_HCD
CONFIG_USB_EHCI_EXYNOS
CONFIG_USB_OHCI_HCD (these OHCI configs will serve the
purpose to use HID)
CONFIG_USB_OHCI_EXYNOS
