The Asus AIO keyboard AK1D was added to hid-chicony based on its USB vendor ID, however images available online suggest that this keyboard is physically branded as ASUS with no mention of Chicony. A recent commit also added support for another Asus AIO keyboard into hid-chicony, this one with USB vendor ID Jess, and a pending review comment asked me to move it into hid-asus because it is also only physically branded as ASUS. I updated the USB ID defines to match the branding and product name, including noting that the recently added keyboard is labelled as ASUS MD-5112.
