Hi,
Got it figured out yet?
Here are some clues and/or opinions if you want/need them.

Yes, I saw that, and I was suspicious of it, but I had
to do some spec reading before replying.
SET_CONFIGURATION changes the device's configuration value.
Alternate Settings refer to optional Interfaces, not
to optional Configurations.
Maybe you should be using SET_INTERFACE instead.
A bit confusing, eh? At least to me.

What is "legacy USB support"?

Sure, good idea. What is your USB interface?

~~~~~~~~~~~~~~~~~~~~~~~
Can you fix (modify, repair) the device's descriptor(s)?
bConfigurationValue should be 1 (or at least non-0) here, not 0.
bConfigurationValue should always be non-zero.
See USB 1.1 spec, section 9.1, USB Device States, and the
SET_CONFIGURATION request, in which config_value == 0
has a special meaning.

~~~~~~~~~~~~~~~~~~~~~~~~
The device doesn't have a config descriptor with bConfigurationValue
== 1, but it probably should have one.
