Fanatec CSL Elite Wheelbase - USB B Port Repair

[mgrharry]

Fixing a usb b port that was damaged and some of the traces were pulled off. Trying to sort out where to run jump wires. There's an USBLC6-2SC6 ESD directly behind the port, datasheet here.

Looking at what's left of the traces it seems like pin 1 on the USB port should go to pin 5 of the ESD chip, and pin 2 of USB should go to pin 1 of ESD, pin 3 of USB should go to pin 2 of ESD, and pin 4 of USB should go to pin 3 of ESD.

Is that correct? Brain not working....

Hi. See attached.

1) Start with reviewing if the TVS ESD device is following the recommended PCB layout from ST Electronics. Most likely it will be.

Check with your multimeter in resistance mode (2k scale). NO power to the logic board. Check if the pin # 1 is indeed D+in and goes to D+out on pin # 6 as per attachment.

The L400 component right behind this ESD TVS diode array is an EMI filter.

It will have 4 pads (2 close to this ESD TVS diode array & 2 pads away from the same part). This EMI filter is a coil to remove electromagnetic interference while passing through the high speed data traffic signals.

One of the 2 pads will be the D+ line from the USB connector. The other of the 2 pads will be the D- line.

You can use this for guidance. Once you have this sorted out, then will follow the Vbus line and finally the ground connection.

Draw up a diagram and post it is here to move forward.

(PS: We design USB products for the PC industry and use similar parts in our product designs)

Sorry for the poor thread title, not sure how I can rename it.
The device is a Fanatec CSL Elite Wheelbase.

Thank you mon2 for the nudge in the right direction. image attached shows the correct layout.

Yes, agreed. Just confirm that on the ESD device (UL26), the location for the ground matches for your PCB layout.

That is, ground on the ESD device = mates with ground on the rest of the board.

Respectively, you have confirmed the position of +5V for this USB connector on the same ESD device.

Otherwise, wire up as you have shared.

Confirmed and tested to work. Thanks folks.
