Description
This device is 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_VEN) in IOS58. It appears to be able to generically address devices via OHC1 or EHCI. It is accessed via several ioctl/ioctlvs. This information is incomplete, please fill it in when possible.
