Hi.

I have a Zoom R16 which audio interface part doesn't work with linux.

I have added following lines to usbquirks.h: /* Zoom R16 */ { .match_flags = USB_DEVICE_ID_MATCH_DEVICE, .idVendor = 0x1686, .idProduct = 0x00dd, .bInterfaceClass = USB_CLASS_AUDIO, },

But it doesn't work.

If I try to play a file with mplayer:

$ mplayer -msglevel ao=9 -ao alsa:device=hw=2 piisi.mp3 MPlayer UNKNOWN-4.4.1 (C) 2000-2009 MPlayer Team mplayer: could not connect to socket mplayer: No such file or directory Failed to open LIRC support. You will not be able to use your remote control.

What can i do to make it work? I have a wireshark log of a winxp session. Does it help a bit?

Thanks for any advice.
