That patch isn't in linux-omap GIT ...

As opposed to a Mini-A to Mini-B cable, or a
Mini-A to A adapter plus a standard A-to-MiniB cable?

There are some omap_udc patches that haven't yet been pulled
down from kernel.org ... i.e. 2.6.21-rc5 has them, but not
the 2.6.21-rc4-omap1 code.

ENOTTY == 25 so I'm guessing "usbtest" hadn't yet
bound to that device. Maybe you're using ancient
versions of /sbin/hotplug? See if it includes
something like:
if [ "$ACTION" = "add" -a -n "$MODALIAS" -a ! -L /sys/$DEVPATH/driver ]
then
modprobe -q $MODALIAS
fi
before it talks to udev.

Where EHOSTUNREACH == 113 which suggests the device is
suspended. It could be that you need more of the usb
updates ... I don't know if that RC4 version has the
relevant "autoresume" updates.
All I can say is that the last time I tested musb_hdrc
against omap_udc it worked just fine. That involved
the omap_udc patch referenced above, and didn't involve
the patch adding "mode selection" ... it was using the
cable based role switching (based on ID pin sensing).
When I get a chance I'll try that on an H4 + TUSB setup
with the latest patches.

All seems fine ...

ISTR test #13 is ISO, so it shouldn't work with gadget zero.

Use the test script you found on the "usbtest" webpage,
it passes a better set of parameters to test #14 ... the
default parameters don't work with that test on gadget zero.
(Which is fine, since all tests use the same default values.
There's no reason to think they wouuld always work.)
