Not as far as I know.

In some ways eCos and USB host support do not really go together. USB
involves plug and play so you cannot know in advance what USB
peripherals may get plugged in - including ones that have not even
been invented yet at the time you ship your eCos-based product. This
implies that you will need to load appropriate device drivers at
run-time, and eCos does not support dynamic loading of code.

There may be specific applications where this does not matter,
especially if you know in advance exactly what is going to be
connected to the USB bus, but for a general-purpose host solution you
would be looking at something like embedded Linux rather than eCos.

Of course when it comes to developing USB peripherals, eCos may well
be a sensible choice. Red Hat has recently contributed USB slave
support.
