I have had same issues with Hummingboard2, the MC7455 needs the pins taped
to be able to be recognized. The EM7455 has been working well with
M.2->mPCIe adapter, and most likely for the same reasons that it does not
let the USB3 signals through.

However, in the latest firmware for MC7455, 02.20.03.00, there is an
feature added with following description:

"Added feature to force the module to use USB 2.0"

But I have not been able to find any information how I use this feature.

Sebastian
