TUSB8020B: Android driver

Part Number: TUSB8020B

Hi,

We have designed TUSB8020B as a USB hub on the board that using Android OS.

This Android OS version is 7.0.

But there is a detection problem when USB memory or SSD is inserted at USB downstream port, and also there is the same problem when it is tested with EVM.

There is no problem when it is tested with PC and EVM.

Isn't this chip(TUSB8020B) supported the Android OS? or Is there any driver supporting the Android 7.0?

Regards
Jeffrey
