Unfortunately as of now on that board EHCI doesn't work.

That's not a problem of a particular USB device but something in either
ECHI host controller or its integration. I do hope we will fix it sometime soon
(this is a development board and USB controller is implemented in FPGA so
there's a chance to fix stuff later on).

So given only OHCI works on the board I went forward and attempted to use it
with Wi-Fi USB dongle.
