+It is implemented by a module (USB_VEN) in IOS58. It appears to be able to generically address devices via OHC1 or EHCI, by way of ioctl calls to /dev/usb/usb. It is accessed via several ioctl/ioctlvs. This information is incomplete, please fill it in when possible.
+All buffers must be in MEM2 (addr > 0x10000000) and aligned to a 32-byte boundary. For all of the ioctlvs, the first buffer must be 64 bytes long.
