A cc=4 is a "USB Transaction Error".  So, it looks like the device is
being quirky.

Is it possible you could try different types of USB3 drives in this
machine?

Ideally, SeaBIOS would have generic USB retry logic to try and handle
weird errors like this.  It's a bit of work to implement that though.
