TUSB7320: No Super Speed and High Power Draw on 1.1V

Part Number: TUSB7320

Hello,

I have designed a board using two TUSB7320 devices. The host is an embedded Intel i7 running Ubuntu 18.04.

The first issue is that the 1.1V input on both devices are drawing abut 0.6A each all the time. Both TUSB7320 get too hot to touch.

The second issue is that when a super speed device is attached, it only comes up in USB 2.0 High Speed mode (480Mbs).

I have seen some other forum posts on these topics but do not see a solution in any of them.

Can someone help?

Thanks
