I'm having trouble charging and USB-C voltage issues

[ErnestZCXu]

Hello
I have implemented this project through JLCPCB
Currently available on ROG Ally
But I have the following problem:

1. ROG Ally is not charging after connecting to XG Mobile Station
2. After I connected the Hub to the USB-C interface of the XG Mobile Station, it could still operate at first (such as wireless keyboard and mouse), but then the Hub seemed to be burned...including the wireless receiver...
3. When running 3DMark, sometimes Windows displays white text on a blue background.

Could the above problem be caused by something incorrect on my part?
The equipment I use is as follows:

• Board: Please refer to the attachment
• Cable: https://en.accessoires-asus.com/laptop/cable/divers/asus-connection-cable-75-cm-62505-84262.htm
• Firmware: ST-LINK v2 (official version)
• Console: ROG Ally (2023)
• Power supply: Standard 500W ATX
• Graphics card: GTX780 (for testing, expected to be paired with RTX4080 Super)

Did you follow https://github.com/osy/XG_Mobile_Station/blob/main/Docs/Build_Guide.md ? You need impedance control:

I don't know if it can be recycled.

I don't remember what parts list I uploaded but I realized after testing that J14 (the 8 pin connector) is not needed and just the 24-pin is enough to power the board. That can save you a few dollars.

Marvelous
So how do I remove J14?
Currently I only know that the 8 pin connector is an additional part that needs to be purchased.
Can I just ignore the J14 material shortage message and order the PCB?

OSY I notice the impedance control set in your image does not match the one in the guide, would this need to be updated? what's the difference?

@moni11811 sorry, the image is from a new revision that isn't released yet. Please follow the guide for accurate information.

For USB:

What hub are you using? Does it work connected directly to the Ally? Does your hub support PD passthrough?

[ErnestZCXu]

TP-Link UE330

[osy]

That doesn't have PD passthrough. How are you powering the Ally?

[ErnestZCXu]

Ally power comes from USB-C?
I thought it was from an ATX power supply
However, I also tried connecting USB-C to the Ally original charger.
It was not charging at that time

[osy]

Like I wrote above, the dock does nothing with USB-C expect pass it through to the external port. It acts like an extension cable. I also pointed out that unlike standard USB-C cables, the orientation matters so you need to make sure the cable is not upside down. If that still didn't work for charging, you should take a picture of your setup because you might have not connected everything correctly.

I understand
I guess I won't test it until I get the reordered board
I'm still worried that other USB Hubs will malfunction due to this
After all, the previously used TP-Link UE330 and keyboard and mouse receiver have been determined to be unusable.
