Usb otg continuity tester

Hi all Adruino pros,
I am able to make a simple 4pin continuity tester using Adruino Nano board for USB 2.0 type A cable. But it fails testing cable with OTG that has 5.1k pullup. Please advise.
Thanks

Need a bit more info than that !
Circuit ?
OTG ? Supported by nano ( google)?
Code ?

Mr google found

You should be looking for continuity, not a level (through the resistor).

Interesting, It appears on the annotated schematic you did not publish the answer you need.
