I simply have not checked into that yet as I will be using it with only mac and windows in the near future.
Ah, sorry for the confusion. I believe that the Linux ALSA driver is now USB Class 2 compliant, which is what I'll verify with the stock xmos board. There are reports of success with xmos as well as the Ayre QB-9 in async mode, so it seems likely to be OK.

I'm planning on getting an TP USB board when available for use under Linux as well and will report on that, but if history is any indication assuming that one will get in on the 'ground floor' of a desirable TP offering can be a poor bet :-)

Hi Russ,

In a previous post you said the usb module will do stereo for the first rev ?
Does it mean that the first rev board will be upgradeable later to do multi channels or is it planed for another board ? That is, will we need new firmware for the usb xmos module or a new module ?
I am following my idea to go bi amplification or tri amplification with two or three boards. Does the usb module will be able to drive two boards (i think since it is possible to put two buffalo boards in parallel for one i2s) and what about three boards ?
Ok, the most important point is how to achieve bi amplification or tri amplification.
Thanks for your attention.

This usb board is great news! I look forward to the outcome.

I would have a question though. Could you please give some details regarding the isolation method? I know there are several discussions regarding isolating usb on various threads here on diyaudio, but no viable solution emerged. Can you share some details?

Thanks and good luck with the development.

Default Bluetooth usb dongle


Russ, is it possible to integrate with your USB transport a Bluetooth sound gateway (like in new home cinema amplituners) using 1$ Bluetooth USB dongle available on ebay? - so we'll able tu use Buffalo DAC wireless!


P.S.With Bluetooth there is total galvanic isolation

I have seen an adapter that allows you to transport USB over Ethernet, transparent for the end devices (they see it as only an usb cable), so there should be similar solutions for bluetooth or wifi.

What scared me is the lowish data rate for bluetooth. Anybody knows what is the maximum data rate in an standard enviroment? I am not meaning in theory, but in practice.

diyAudio, doing it as big as you can, JUST BECAUSE WE CAN!

Popular Bluetooth v2.0 +EDR allow 3mbit/s which is sufficient for Red Book, hi-res tracks will require Bluetooth v3.0 (up to 24mbit/s).
