Yes, we tested this when we did the port.

What sort of acknowledgement do you expect?

Did you run "dmesg" or "tail -f /var/log/messages" to look for kernel
messages?

If you were expecting some kind of hotplug support, did you start the
udev services by running "/sbin/start_udev" ?

Last but not least, are you sure your kernel configuration is
complete? For example, you must have enabled SCSI support and SCSH
disk support.

Then OTG is not what you're looking for - but  we  definitely  tested
host mode, including tests with mass storage devices.
