It doen't look like you have USB HID turned on in your kernel.
Here is what I have for the USB portion of my kernel config:
CONFIG_USB_ARCH_HAS_HCD=y
CONFIG_USB_ARCH_HAS_OHCI=y
CONFIG_USB=y
CONFIG_USB_DEVICEFS=y
CONFIG_USB_EHCI_HCD=m
CONFIG_USB_OHCI_HCD=m
CONFIG_USB_OHCI_LITTLE_ENDIAN=y
CONFIG_USB_UHCI_HCD=m
CONFIG_USB_PRINTER=m
CONFIG_USB_STORAGE=m
CONFIG_USB_HID=m
CONFIG_USB_HIDINPUT=y
CONFIG_USB_WACOM=m
CONFIG_USB_EGALAX=m

If that doesn't work, maybe try to plug it directly into the computer
instead of the hub. I've had devices not like being plugged into a hub
before.

For what it's worth, here is what I have showing up in dmesg when I plug
my tablet in:
ohci_hcd 0000:00:02.0: wakeup
usb 1-1: new full speed USB device using ohci_hcd and address 2
input: Wacom Intuos2 6x8 on usb-0000:00:02.0-1

cat /proc/bus/input/devices shows this for the tablet:
I: Bus=0003 Vendor=056a Product=0042 Version=0126
N: Name="Wacom Intuos2 6x8"
P: Phys=usb-0000:00:02.0-1/input0
H: Handlers=mouse2 event4
B: EV=1f
B: KEY=1cdf 0 1f0000 0 0 0 0 0 0 0 0
B: REL=100
B: ABS=f000163
B: MSC=1
