I have a CJMCU-204 4-Port USB hub. In addition to 4 type A ports it has a 6-pin header, labelled VCC, DMU, DPU, GND (which may be for a possible 5th port) and SDA & SCL.
The board's chip is labelled "FE1.1s usb 2.0 hub LV3P908810276C".
How are SDA and SCL used? I've searched and found places that sell the hub, but none have any details or documentation.
Thanks,
Jim
