Mcmaster USB extension not recognized as hub

Hi everyone,

Ran into an issue a while back where the USB device I had plugged into a USB extension cord wasn't recognized by my teensy 4.1 . The same device plugged directly into the teensy did work and I could read the I2C output from the device.

Here's the extension cord: https://www.mcmaster.com/1156n23/

I've also tested the extension cable and ensured it works.

Any guidance in how I can have the teensy skip over the extension and read through the hub would be appreciated! Thanks.
 
USB 1 and 2 are rated for 5m cable maximum, USB 3 for 3m maximum. That cable is out of specification for USB. Do you need such a long extension (there are apparently active extension cables which might be better for that).
 
This is being used in an industrial environmentso I need it to be quite long to reach my PC and Teensy board from inside our metal 3D printer. I believe this is an active cable (?) in order to reach those lengths. I confirm the extension cord functions at those lengths with my PC, but not with the Teensy board. The cable is seen as a hub by the Teensy so I can confirm it's being powered correctly, but it won't recognize any device connected to it.
