New firmware release for USB Audio 2.0 Reference Design

Postby jason » Thu Mar 04, 2010 10:47 am

Just a quick update:

The latest firmware release (1v45) for the USB Audio 2.0 Reference Design (XS1-L1) is now available from XMOS.

The release includes the beta release 0.31 of the Windows Audio Class 2.0 driver from Thesycon, which provides ASIO support.

For further details please contact XMOS.

I have updated the flash and the Win driver to the new one.

If you connected the Audio-card to a USB 1.X HUB with the old driver set (Maybe without you knowing it due to connection to a desktop computer with many mixed USB 1.1/2.0 ports), Windows just reported some error like "failed to start USB device" , instead of "This device can perform better under a USB 2.0 HUB".

That compatibillity issue seems to be solved in this one.

Will check if I can make it enumeratate as an ASIO 2.2 device. It didn't work yesterday when I tried with a tool compiled under the ASIO 2.2 SDK.

Which ASIO version does it support ???

Do you need multi-platform, multi-OS (Windows, Macintosh (8,9,X), Unix (OSS), SGI, and BeOS), multi sound-driver, x86/x64, full-duplex, multi-channel low latency support, free open-source audio I/O library, in your PC program ?

Would you like to skip learning the Steinberg ASIO SDK, WMME and DirectSound ??

Check out http://www.playrec.co.uk/

Makefiles for MATLAB and Octave 3.0 are available freely, and you can check out the PortAudio for usages with other languages.

Just checked playrec.co.uk seems like great tools, good forum.
What is Matlab basically, is it expensive? It is like a Mathematica?

It's quite expensive.

I use Scilab occasionally:

http://www.scilab.org/

It's free, and can import MATLAB programs. Octave is also free and is largely compatible with MATLAB.

MATLAB is focusing on numeric computations.
MATLAB was a short for MATrix LABoratory in the earlier days - written by a Professor in Lin Alg in the 1970 for education purpose.
Today MATLAB has alot of toolboxes, C-code export for embedded targets, JAVA support with others.

Linear Algebra is a nice way of doing things.
glossed over the scilab and octave site, I definitely
shall give them a try. Thanks for quick your responses.

Back to the audio board :-), one thing I noticed with this new software (and the previous for that matter) is that it seems to not want to change sample rate, at least not using Audacity. It may be a Audio 2.0 issue though, I hacked the code in the previous release and got it working using Audio 1.0, and the speed change was coming through ok then. The driver seems to mention a control app, but I haven't found that yet.

The installer will install the .exe tools called

TUSBAudioCpl.exe
tusbaudiospy.exe

(Default is C:\Thesycon\TUSBAUDIO\v0.31.0)

but the installer doesn't create any desktop shortcuts to the .exe files.

You will find your answers in the TUSB control panel!
