Dear Mr. Watanabe:

You can download the specification from:
http://www.usb.org/developers/devclass_docs#approved
The download contains an example: USB_Video_Example_1.0.pdf
You may want to download
http://www.microsoft.com/whdc/device/stream/vidcap/UVCView.mspx to check
your descriptors.
Hopefully this will help you get started.

Thank you,

I downloaded USB_Video_Example_1.0.pdf and UVCView.exe.

I tried to make a firmware by first descriptors wrote in this pdf.
and I tried to UVCView.exe.

what is [ Multi-interface Function code 239 used for device with no IAD
descriptors ] ?

UVCView.exe said to

If "*!*ERROR: No open pipes!" then "*!*ERROR: Multi-interface Function
code 239 used for device with no IAD ".
This could be the result of a bug in the older versions of UVCView.
Please contact me directly if you would like to try a newer version of
UVCView.

I can't understand howto to contact you directly.

At least, I passed over this error message.
I'll think to next error message.
