This device is internally used to communicate with the USB camera provided with the game "Your Shape". Not much information is known at this time.

It is implemented by a module (USB) in IOS58. It appears to be able to generically address devices via /dev/usb/oh0 and /dev/usb/ehc. It is accessed via several ioctls. Yes, I know this doesn't match up with the ioctls called by /dev/usb/ven; sorry!
