It doesn't look like you have the HID keyboard version. I have an ID
Tech IDT4439U which when plugged in behaves like a keyboard. In the
following lsusb output, notice the iConfiguration and bInterfaceClass
parameters. My wild guess is you will need a driver. Also you may want
to verify you have CONFIG_HID* enabled in your kernel config.
