Hi Bryant,
1. You can refer to the TPS65987EVM with the 10G-EXPANSION-EVM for a Docking design using TPS65987D and TUSB1046. We do not have a design including the TUSB8044 but it can be added like in your block diagram.
2. No, the I2C master of the TPS65987D…
Hello Subhajit,
DP and VBUS are at the correct levels. Do you see a 24 MHz clock at pins 61 and 62?
For your test, do you just connect the hub? Or are all the downstream devices connected too? Is the hub self-powered or powered from VBUS?

Debugging USB Hubs can be a complex task sometimes requiring an extensive amount of time to debug. Listed below are some simple questions to ask when beginning debug on your design.
Was the USB hub enumerated by the USB Host?
To check, open your device…
Hi Eduardo,
The TPS65987D does not support storing billboard strings. However, from looking at the TUSB8044 datasheet in more detail, it appears they can store the billboard strings in their external EEPROM. I would suggest asking a new question with…
Hi Onawa-san,
1. The TPS65987D has a GPIO event for "Billboard Event" That that the customer could use for determining when there is a Billboard event needed.
2. If using the TUSB8044 with the TPS65987D you could tap the D+/D- lines onto the…

Why not use the TUSB8044? It provides simultaneous SuperSpeed (USB3) USB and highspeed/full-speed connections (USB2) on the upstream port
and provides SuperSpeed USB, high-speed, fullspeed, or low-speed connections on the downstream ports.

A block diagram should be something similar to the block diagram of the TUSB8044 on the first page of the datasheet. A block diagram of the hardware that shows how all the hubs are connected, that would be helpful.
Part Number: TPS25740 Other Parts Discussed in Thread: TUSB8044 , TUSB321 , , TPS65981 Hello,
We are working on a new design with Galaxy S8 ( as a host ) and we using USB 2.0 \ 3.0 interface with it and the USB HUB ( TUSB8044 ) by a Type C connector.
We need…
