We have until the end of June to make ourselves heard. Currently there are 4 different versions in circulation and the head of development wants to cut that down to one. So we should do some testing with regards to latency before they make the final decision. I'm assuming that the URB code is relevant to Audio latency. -- Patrick Shirkey - Boost Hardware Ltd.

Excellent work. as you already know, it's not me but the update of usb modules :) anyway, could you check again whether the driver works? just taking a look at the lsusb output, the device has no mixer units. there are only input/output terminals. so, don't be bothered even if you see no mixer controls.

If so then can you use the descriptor info to hardcode them in? On a side note I would really like to know how you use the descriptor info to write a driver. You asked me for the same thing when you were doing the cmipci driver. It would be a valuable additon to the developers documentation. Something like "Using the information provided in /proc/asound to write a driver". If you/Paul/Jaroslav/Abramo or anyone else who grok it could write up some quick notes I will gladly incorporate them into the online docs. I am going to write up some info now on the installing the usb-audio driver and add it to the wiki. -- Patrick Shirkey - Boost Hardware Ltd.

Currently I still use the /proc interface but I don't have concrete understanding of the difference between the two yet. fromwhat I gathered you have to specify devfs in the kernel for it to be used.

Is that correct? yes. let me rephrase: if you use devfs interface for /dev, you cannot use the 2nd or later card with the original sound_core.c on 2.4 kernel. if you use proc interface for /dev/snd, it works anyway. also - if you build the kernel with devfs support and use 2nd or later cards, then you'll get annoying error messages, even if you use proc interface. (it's harmless, though.)
