As with the 0202 and 0404 USB, functionality is very limited: just a couple of sample rates, no volume/mute control, etc. Signed-off-by: Eran Tromer --- sound/usb/usbaudio.c | 3 ++- sound/usb/usbquirks.h | 7 +++++++ 2 files changed, 9 insertions(+), 1 deletions(-) diff --git a/sound/usb/usbaudio.c b/sound/usb/usbaudio.c index 410be4a..0cc6fd5 100644 --- a/sound/usb/usbaudio.c +++ b/sound/usb/usbaudio.c @@ -481,7 +481,7 @@ static int retire_playback_sync_urb_hs(struct snd_usb_substream *subs, } /* - * process after E-Mu 0202/0404 high speed playback sync complete + * process after E-Mu 0202/0404/Tracker Pre high speed playback sync complete * * These devices return the number of samples per packet instead of the number * of samples per microframe. @@ -2261,6 +2261,7 @@ static void init_substream(struct snd_usb_stream *as, int stream, struct audiofo switch (as->chip->usb_id) { case USB_ID(0x041e, 0x3f02): /* E-Mu 0202 USB */ case USB_ID(0x041e, 0x3f04): /* E-Mu 0404 USB */ + case USB_ID(0x041e, 0x3f0a): /* E-Mu Tracker Pre */ subs->ops.retire_sync = retire_playback_sync_urb_hs_emu; break; } diff --git a/sound/usb/usbquirks.h b/sound/usb/usbquirks.h index 82a8d14..b90d98b 100644 --- a/sound/usb/usbquirks.h +++ b/sound/usb/usbquirks.h @@ -62,6 +62,13 @@ .idProduct = 0x3f04, .bInterfaceClass = USB_CLASS_AUDIO, }, +{ + /* E-Mu Tracker Pre */ + .match_flags = USB_DEVICE_ID_MATCH_DEVICE, + .idVendor = 0x041e, + .idProduct = 0x3f0a, + .bInterfaceClass = USB_CLASS_AUDIO, +}, /* * Logitech QuickCam: bDeviceClass is vendor-specific, so generic interface
