| Set up a device insertion/removal callback. Returns the number of entries.
When a callback is triggered, the manager is locked to the caller handle and will not trigger other callbacks until AttachFinish is called. Other handlers will receive an IOS_EINVAL when attempting to modify device information.
Note that this ioctl immediately returns on the first call.

| The caller handle must match a stored ID (?)
| Unlocks the manager from the current handle, triggers change callbacks for the other active handles and issues /dev/usb/usb ioctl 1 in some cases.
If it does, IPC_SUCCESS is returned, change callbacks are triggered and /dev/usb/usb ioctl 1 is issued.
If the caller handle does not match the one that locked the manager, IOS_EINVAL is returned.

Calls /dev/usb/usb ioctl 4. If the call was successful, updates the internal device struct to reflect the state change. The new state must not be the same as the current one; otherwise IPC_EINVAL will be returned.
