Appears to be a way to address usb devices via EHCI (USB 2.0). This driver has only been seen in IOS58. The interface appears to resemble that of /dev/usb/oh0.

ASIX AX88772 USB2.0 to Fast Ethernet Adapter (referenced in IOS eth driver)

IPC request list

number name Description
0x01 IOS_OPEN Opens the device. Can only be opened from PID 17 (USB_VEN) otherwise returns -1. Returns 0 if success. Returns 1 if device already open (not confirmed)
0x02 IOS_CLOSE Closes the device. Returns 0 always.
0x03 IOS_READ Does nothing. Returns -4.
0x04 IOS_WRITE Does nothing. Returns -4.
0x05 IOS_IOCTL Does nothing. Returns -4.
0x06 IOS_IOCTLV Send an ioctl request.
