Part Number: TUSB8041A
Other Parts Discussed in Thread: TUSB8041, TUSB8041EVM

Hi everyone, sorry for my poor english.
I use TUSB8041 for a TYPE-C dock design , type-c port convert to HDMI+USB 3.0( x4-port)+RJ45 100M network port.
4 USB 3.0 port+1 RJ45 100 M network ports i use 2 TUSB8041 chips.
The dock desigen scheme is: VL171+TUSB8041(x2)+CS5261+SR900AI.

The TYPE-C female interface is used. The USB3.0 interface uses the TYPE-A female interface

VL171 is a type-c interface bidirectional commutator chip

TUSB8041 is the USB3.0 HUB chip, and two chips are cascelled. Chip A uses 3 downstream USB3.0 ports and the other 1 downstream USB3.0 port is connect to the upstream port of chip B. Chip B uses only 1 downstream USB2.0 ports to connect to the USB to network port chip SR900AI.

The CS5261 is a 2-wire DP to HDMI chip. (HDMI function is displayed normally)

The SR900AI is a USB2.0 to network conversion chip (not work yet).

The current situation is that the computer can recognize 2 superspeed USB hubs. (as picture) However, all 4 TYPE-A USB interface can not be used, the computer does not recognize any USB flash drive or other usb devices. Attached pdf file is the dock schematic, please help to me to find out where is incorrect。 Thanks

Hi Brian:

I check win10 Device manager list, the superspedd usb hardware id is show as below picture.

VID_0451&PID_8140&REV_0100 . the other one is same too.

Hi Brian:

Tanks for you time. I try USBtreeview, I use a USB stick to test 4 downstream ports.
port1,2,3(from TUSB8041 chipA) nothing show up(try 5 times).
port4(from TUSB8041 chipB) sometime will show up( try 8 times, 2 show up). but the show up state is always changing, this second is: kingston 1666, the next second is: unknown Device, the next second is:Kingston DataTraveler 3.0 USB Device......... (just as picture show)
could you please help, why does this happen. Bad power? or bad routing? I attach my PCB pcb routing

Regards

it looks you only see USB3 hub, there is no USB2 hub.

what is U2?

Hi Brian:

U2 is a USB type-A female connector. how do you think where is the problem? Thanks.

Hi Brian:

Vbus_in is coming from J3, the upstream USB TYPE-C female connector VBUS_5V. VBUS 5V voltage is ok.

Hi Brian:

Thanks for you time. I just sent a friend request so we can discuss more details。

I make a new PCB version again for comparative test. This time, we will use CS5266（an other DP to Hdmi chip）+TUSB8041 (TUB8041 circuit do no change )for comparative testing. If there is any progress, I will update it here.

Hi Brian:

The new PCB(CS5266) version test results is same, the pc can recongnize 2 universal superspeed USB hubs, but USB devices can not be used.

Is there a way to test TUSB8041's current working status or register value?

Hi Brian and other who might pay attention

Latest development, after I replaced the TYPE-C cable, Windows 10 successfully recognized 2 USB2.0 HUB+ 2 USB3.0 HUB(as pic). But at present, it seems that the downlink USB port can only use USB2.0 devices, and USB3.0 devices cannot be used.
The faulty TYPE-C cable is a cause, and I'm checking the PCB layout，i will update the progress later

Hi Brian and other who may pay attention

I used the same TUSB8041 circuit to independently make a HUB PCB for testing, the hub test is OK, USB3.0 and USB 2.0 work fine. So TUSB8041 chip and TUSB8041EVM circuit is OK, it works.
There is a problem with my application, which may be caused by PCB routing, or poor quality of USB3.0 connector or PCB SMT production problems.
So this discuss can be closed. Thank you Brian Zhou and TI team guy
