I have:

CONFIG_USB_SUPPORT=y
CONFIG_USB_ARCH_HAS_HCD=y
CONFIG_USB_ARCH_HAS_OHCI=y
CONFIG_USB_ARCH_HAS_EHCI=y
CONFIG_USB=y
CONFIG_USB_DEBUG=y
CONFIG_USB_ANNOUNCE_NEW_DEVICES=y
CONFIG_USB_DEVICEFS=y

CONFIG_USB_SUSPEND=y
CONFIG_USB_MON=y

CONFIG_USB_EHCI_HCD=y
CONFIG_USB_OHCI_HCD=y

CONFIG_USB_OHCI_LITTLE_ENDIAN=y
CONFIG_USB_UHCI_HCD=y

CONFIG_USB_PRINTER=y

[    2.409578] ohci_hcd: USB 1.1 'Open' Host Controller (OHCI) Driver
[    2.409826] ohci_hcd: block sizes: ed 80 td 96
[    2.409851] uhci_hcd: USB Universal Host Controller Interface driver
[    2.410158] uhci_hcd 0000:00:1a.0: PCI INT A -> GSI 16 (level, low) 
-> IRQ 16
[    2.410411] uhci_hcd 0000:00:1a.0: setting latency timer to 64
[    2.410413] uhci_hcd 0000:00:1a.0: UHCI Host Controller

The first two lines are the only ohci lines in dmesg.  Many more usb 
messages e.g. hubs, etc

I really didn't pay a lot of attention to USB when configuring.  I only 
use the USB for mouse and keyboard, and *very* occasionally for an 
external drive.  My printer is is USB, but that is on my wife's ubuntu 
system.
