From what I understand so far, USB allows a device to have multiple
"interfaces", in which each interface specifes the class of device, number
and id's of the endpoints, etc...

From what I understand so far (hereafter abbreviated as FWIUSF), eCos will
pretty much allow me to do whatever I want in USB land -- it currently
provides support for some common client level USB transactions that must be
supported by all devices, and a sample ethernet-on-top-of-USB driver.

FWIUSF, eCos supports multiple interfaces on devices, so it should support
MSD and HID at the same time.

We are using the OMAP5912 from TI.  I think Paul submitted some patches not
too long ago in preparation for submitting our HAL.  I anticipate submitting
our HAL to CVS sometime in the near future.
