    initial v1  
    11Hi waddlesplash, I'm curious if you own usb2.0 external audiocards? I've got two over here which I use to make music via Jamulus. These are both 2.0 spec, and do not work yet with usb_audio.

    3 Maybe most notably on the samplerate stuff since you now use clock sources with multipliers and divs to set the rate somehow, I don't understand that yet.
     3I am tweaking a bit with that driver to see if I can get sound out of one of those, but it turns out probably a bit serious work has to be done for the 2.0 spec. Testing on EHCI upto now, and indeed I just stumbled upon the double locking panic (though outbound transfer I just saw are not yet supported on EHCI)

    78Using a behringer U-phoria UMC202HD (costs around 65 euro's, german brand, quite good actually) I get input sliders after tweaking the driver, and also output buffers are generated and tried to exchange (which results in the panic).
