I am trying to find a good solution to connect several - possibly a dozen - Teensy nodes to a PC host.
The simplest approach would be to just connect them wired, to a USB hub, and run both power and serial.
However, eventually I will have to run wire lengths up to 10m and possibly beyond.
Is this even possible with stock USB2 cables (I found 25' max so far)? For power, data, both?
I might also have to add a power supply to each node (either because I can't run USB 5V that far, or because each nodes needs more than what the Teensy 3V3 regulator can supply anyway).
Does this still apply - mechanical modification of USB cable (cut red 5V) or Teensy (pads) is necessary?

For Teensy LC and Teensy 3.5/3.6 ?
I looked for data-only USB cables, all I found was:

Is there any retail or DIY solution for "networking" a bunch of Teensies, or putting them on a bus?
Is there a better than "Serial" connection between PC and Teensy, over USB? Or would it make sense to investigate actual RS232 solutions?
