Landuage ID (String0 Descriptor)

[alexz]

Talking about the USB design, String zero descriptor.
Where can I get the table of language codes like for example:
Supported Language Code Zero
(e.g. 0x0409 English - United States)
Supported Language Code One
(e.g. 0x0c09 English - Australian)

I need other languages as well.

And another question, if I can:
in the CCS example code of USB,
why there is '0' defined after every character in string descriptors,
which makes the lengths of strings almost twice longer?

Thanks a lot

Alex,

The supported language is an operating system thing. I don't believe it has anything to do with the USB operation. See the Microsoft page at http://www.microsoft.com/globaldev/reference/oslocversion.mspx for the most current list.

Did you read the USB spec about this subject

In paragraph 9.6.7 of USB Specification v2.0, the list of LANGID's is mentoined.

Yes, I have found it now, thank you.

Does anybody know what exactly the string indexes are in the device descriptor field?
And how it works with strings you define?
I have seen in the CCS example, those are defined as 1,2,0.
What does it mean? How can it point to strings?
