uPD720201 - USB3.0 disconnection

Hi, everyone.

I am working on a project that uses uPD720201.

I am not solving one problem.

Please give me some advice.

The symptoms of the problem are as follows.

If USB3.0(SS) device is connected to one port and USB2.0(HS) device is connected to the other port,
USB3.0(SS) is disconnected within a few minutes.

Other combinations do not cause problems.

- Port 1 : SS, Port 2 : SS -> OK

- Port 1 : HS, Port 2 : HS -> OK

- Port 1 : SS, Port 2 : FS -> OK

- Port 1 : SS, Port 2 : HS -> NG

For reference, the USB compliance test was passed.
