USB connection problem with JDM-020 and JDM-030

[kaitsu]

Hello everyone, I have the same problem on 2 different controllers JDM-020 and JDM-030. The controllers are not recognized by USB cable. They charge the battery correctly and I can connect them in bluetooth but impossible by cable. I changed the USB pcbs with new ones. I couldn't find any threads with this problem. Do you know what component can cause this failure? Thank you very much

Hi there, I have exactly same problem with my JDM-030 controller. Did you find solution ?

Remove the TVS Diode protection chip for the USB data lines and see if they work then. On the -020, it's on the top side of the motherboard, small 5 pin chip just above the left stick. On the -030, it's on the bottom side of the motherboard, 5 pin chip just below the connector that goes to the USB/LED board.

Hi, same for the JDM-040? I have one that does charge and have +3v on data lines but still not detected via usb. On pc windows detects an unknown device.

It's worth a try, if it doesn't work you can always put it right back on. It's in the same place as the -030, just under the connector there.

Also note, the -030 has another 5 pin protection chip on the USB/LED board, could be that one is bad versus the one on the motherboard.

Hi.

TVS Diode chip (motherboard side) removed on JDM-030 and it's working again, thanks for the suggestion. Now we need the replacement part, do you have buy link or the part model/name?.
