DJ Connect with djay2 for Android doesn't work

I’m using Djay2 for Android V2.2.4 on Huawei dtab d-01h (Android 6.0).
And connected DJ Connect via USB(Host) Cable, but didn’t work pre-cueing.
Split setup doesn’t work, and pre-cueing setup dialogue doesn’t appear.
When rebooting device, “djay 2 Looking for resources to download” message appear and djay2 crushed.

Is there someone who can use DJ Connect with djay2 for Android?
