Ok, I managed to setup a VBox with "TheOtherOS" and usbmon and sniffed some traffic when I (virtually) plugged in the device. The file is (compressed) about ~620 KiB. I am honest: I have no clue what I sniffed or how I should read GPIO registers from there. If anyone is interested in helping me I would send the file directly.
