eCosCentric can provide this support - it's not in the public tree
at this time.

As for how practical it is - this is a hard nut to crack.  USB host
in general is non-trivial since it's designed to work with many different
client types.  eCos is designed for embedded systems (hence eCos =
Embedded Configurable Operating System).  In this environment, the number
of clients is probably limited, e.g. only a USB FLASH drive, which can make
the problem more tractable.  It's still non-trivial which is why the
only support available at this time (AFAIK) is as a commercial add-on.

n.b. I'm not [formally] associated with eCosCentric.
