The USB Audio 2.0 Group

Postby lilltroll » Fri Jan 15, 2010 4:43 am

I have been contacted by many who have bought the USB Audio 2.0 Reference card or is thinking about buying it.

Most people seems to have trouble getting started writing code for it - and very few just bought it to only have it as a standard stereo USB-soundcard.

It doesn't have buffered outputs so you cannot even connect headphones to it and listen to music, since the CODEC output should not be loaded below 10 kOhms - at least not under 3 kOhms.


I hereby start this group to make it easier to share knowledge around the card and the software.


So if you have the card or if you are thinking of buing one - welcome to this group!

NEW: The new license model seems to have been released from XMOS.
It seems to be L series chip with the name extension THS:
"Thesycon USB Audio Class 2.0 Production Driver
Full version of Windows driver with customization kit.
Requires purchase of XMOS/Thesycon XS1-L device bundle product (e.g. XS1-L02A-QF124-C4-THS)"

Pay per chip seems to be the thing.
Awaiting some more Public information regarding this matter.

*------------------------------------------------------------------------*

I have been in contact with TheSycon, the company that made the USB 2.0 driver for Windows.

Anyone who wants to know more about the license regarding the driver for commercial use can contact me, and get a copy of the pdf and contact info.
(I'm have agreed to not post it in Public on the web.)

Edit: The "old" license model is out of date.
TheSycon/XMOS will release a new solution regarding driver licenses in the near future.

If you have tried the version 1.5 software in the new tools release (10.4), you will find a few errors. XMOS is going to be updating the reference to work with the new tools. I have not heard any specific release date or timeframe (other than soon).

The new multi channel Audio design uses the two core L2. The soon to be released firmware has code to buffer samples between two cores via an XLINK. Those designing with multi core ambitions, will want to get the new reference design, or get the new firmware.

I am experimenting with an XS1-L1 reference design under Windows. I installed the thesycon drivers and all audio related works fine.
I would like also to access, through USB, the on board I/O available (two pushbuttons and two leds); to do this do I need a dedicated driver?

Several days ago, I found a new version of firmware 1.7.1 on my account and download it.
Several good changes made but some strange codes inside too. Already mail to support of XMOS about the question.

But today, I log-in, found the new version is GONE. There only has version 1.7 there (but the file date is new though)

Did I accidentally download a ghost version? puzzled...

Any one knows the answer?
