Do you have any specific recommendations (maybe an Internet link?)
for a ferrite that can accommodate 10-20 turns of a USB cable? I
own a few ferrites, but the hole is only large enough for a cable
to pass through it a couple times (and frankly, I didn't like how
it felt using the ferrite this way)

Thanks!
