I !think! mine has that too.  This is the usb part of my config:

root@smoker / # cat /usr/src/linux/.config | grep USB | grep =y
CONFIG_USB_HID=y
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_DEVICEFS=y
CONFIG_USB_OHCI_HCD=y
CONFIG_USB_OHCI_LITTLE_ENDIAN=y
CONFIG_USB_ACM=y
CONFIG_USB_PRINTER=y
CONFIG_USB_STORAGE=y
root@smoker / #   

With mine, it tries 2.0 first then goes to the first version.  My
printer is 2.0 but my camera is the old version, or maybe it is the
other way around.  I got a memory stick that connects 2.0 to.  Anyway,
that works here and it may work for you.
