+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!+=== Ioctls ===+

−This device is used to communicate with the USB camera provided with the game "Your Shape".
+Not much information is known at this time.
+This device is internally used by several USB resource managers. Not much information is known at this time.
+It is implemented by a module (USB) in IOS58 that runs under UID 17 (PID_USB). This resource manager can only be opened from that UID. It appears to be able to generically address devices via /dev/usb/oh0 and /dev/usb/ehc. It is accessed via several ioctls.
−Because all of the USB related modules run under the same UID, they all share the same file descriptor table. This allows ioctl 1 (GetDeviceList) to return FDs to /dev/usb/ehc and /dev/usb/oh0. These are directly used by VEN, HID, etc. when submitting transfers, without going through /dev/usb/usb.
