Since i was unable to get any answer on XDA or Lenovo forums, will ask here. ( due to small comutiny where users help each other)

I made USB hub from cypress chip, and it works with my HTC One M8 ( same time USB HID + USB UVC camera + USB Flash, + USB DAC, no difference in sound, just what i need)

But for some reason Lenovo phab plus can't detect USB hub, while it can work in separate with each device. Any idea why ? And how to fix it ? :)

This is what my project needs, and i can't do it without USB hub ;(

wow, i was so desperate that i did something stupid. Put one hub into another, and then connected my own cypress hub to that. And it worked . Can you believe it ?

So maybe USB VID PID was too much off for android to work with it, or what, have no idea.

Now i am happy :D
