If you find issues with the DT on my driver the firmware probably needs to be updated. Unfortunately the idiotic way they versioned the files you have no way to know if its outdated or not since both the original FW and current report the same version back to the hub. There is a post with a link and more info somewhere, I will see if I can find it. Might be a good idea just to push the current firmware to it right away.
Found it, check this post and below it:

And here I explained the versioning confusion / assumptions:
