Clues welcome.
Despite the docs saying the kernel modules can be loaded at boot time rather than included in the kernel itself, there is a difference. I found the ehci driver was not enabled in the kernel build so I did that. Next boot there is a /dev/usb3 device for the ehci. Now I get: RX d'board A: Basic Rx usb_control_msg failed: error sending control message: Input/output error RX d'board B: <none> xfered 1.05e+06 bytes in 0.263 seconds. 3.98e+06 bytes/sec. cpu time = 0.02065 noverruns = 0 which I think means I am getting ~4 MB/s from the RX board test.
