@tehn: Sorry for digging up this old thread, but it looks like I really need this module to make this small setup work (see below) without the dreaded high-pitched whining noise.
It is my understanding that the middle USB mini-B is power input,
the two outer USB mini-B connect to e.g. Ansible’s and White Whale’s USB-A connectors,
and the two USB-A connect to e.g. Arc’s and Grid’s USB mini-B connectors,
correct?
