It doesn't look like you have the HID keyboard version. I have an ID |
| 11 |
Tech IDT4439U which when plugged in behaves like a keyboard. In the |
| 12 |
following lsusb output, notice the iConfiguration and bInterfaceClass |
| 13 |
parameters. My wild guess is you will need a driver. Also you may want |
| 14 |
to verify you have CONFIG_HID* enabled in your kernel config. |
