2011-09-27ALSA: usb-audio: increase control transfer timeoutClemens Ladisch1-1/+1
There are certain devices that are reportedly so slow that they need more than 100 ms to handle control transfers. Therefore, increase the timeout in mixer(_quirks).c to 1000 ms. The timeout parameter of snd_usb_ctl_msg() is now constant, so we can drop it.

2010-06-11ALSA: usb-audio: fix control messages for USB_RECIP_INTERFACEDaniel Mack1-0/+4
Control messages directed to an interface must have the interface number set in the lower 8 bits of wIndex. This wasn't done correctly for some clock and mixer messages.

2010-03-05ALSA: usb-audio: refactor codeDaniel Mack1-0/+32
Clean up the usb audio driver by factoring out a lot of functions to separate files. Code for procfs, quirks, urbs, format parsers etc all got a new home now. Moved almost all special quirk handling to quirks.c and introduced new generic functions to handle them, so the exceptions do not pollute the whole driver. Renamed usbaudio.c to card.c because this is what it actually does now. Renamed usbmidi.c to midi.c for namespace clarity. Removed more things from usbaudio.h. The non-standard drivers were adopted accordingly. Signed-off-by: Daniel Mack <daniel@caiaq.de> Cc: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
