2009-03-02sound: usb-audio: fix queue length check for high speed devicesClemens Ladisch
When checking for the maximum queue length, we have to take into account that MAX_QUEUE is measured in milliseconds (i.e., frames) while the unit of urb_packs is whatever data packet interval the device uses (possibly less than one frame when using high speed devices).

2009-03-02sound: usb-audio: fix rules check for 32-channel devicesClemens Ladisch
When storing the channel numbers used by a format, and if the device happens to support 32 channels, the code would try to store 1<<32 in a 32-bit value. Since no valid format can have zero channels, we can use 1<<(channels-1) instead of 1<<channels so that all the channel numbers that we test for fit into 32 bits.

2009-02-16ALSA: usb-audio - Workaround for misdetected sample rate with CM6207Joris van Rantwijk
The CM6207 incorrectly advertises its 96 kHz playback setting as 48 kHz in its USB device descriptor. This patch extends an existing workaround in usbaudio.c to also cover the CM6207. This resolves issue 0004249 in the ALSA bug tracker. Signed-off-by: Joris van Rantwijk <jorispubl@xs4all.nl> Cc: <stable@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2009-02-16sound: usb-audio: fix uninitialized variable with M-Audio MIDI interfacesClemens Ladisch
Fix the snd_usbmidi_create_endpoints_midiman() function, which forgot to set the out_interval member of the endpoint info structure for Midiman/ M-Audio devices. Since kernel 2.6.24, any non-zero value makes the driver use interrupt transfers instead of bulk transfers. With EHCI controllers, these random interval values result in unbearably large latencies for output MIDI transfers.

2009-02-06sound: usb-audio: handle wMaxPacketSize for FIXED_ENDPOINT devicesClemens Ladisch
For audio devices that do not have proper audio descriptors (e.g., Edirol UA-20), we use hardcoded parameters from our quirks list. However, we must still read the maximum packet size from the standard endpoint descriptor; otherwise, we might use packets that are too big and therefore rejected by the USB core.

2009-01-26sound: usb-audio: make URB sizes more equalClemens Ladisch
Distribute the packets evenly among the URBs, instead of making all URBs except the last one to have the maximum size. This makes the timing of pointer updates more regular and removes some special cases from the code. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-01-26sound: usb-audio: limit playback queue lengthClemens Ladisch
Once our URBs contain enough packets, queueing more URBs does not give us any additional underrun protection (as we use double-buffering) but just increases latency unnecessarily. Therefore, we try to limit the queue length to some reasonable value. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2009-01-04ALSA: sound/usb: Use negated usb_endpoint_xfer_control, etcJulia Lawall
This patch extends 42a6e66f1e40a930d093c33ba0bb9d8d8e4555ed by using usb_endpoint_xfer_control, usb_endpoint_xfer_isoc, usb_endpoint_xfer_bulk, and usb_endpoint_xfer_int in the negated case as well. This patch also rewrites some calls to usb_endpoint_dir_in as negated calls to !usb_endpoint_dir_out, and vice versa, to better correspond to the intent of the original code.

2009-01-01ALSA: sound/usb: use USB API functions rather than constantsJulia Lawall
This set of patches introduces calls to the following set of functions: usb_endpoint_dir_in(epd) usb_endpoint_dir_out(epd) usb_endpoint_is_bulk_in(epd) usb_endpoint_is_bulk_out(epd) usb_endpoint_is_int_in(epd) usb_endpoint_is_int_out(epd) usb_endpoint_num(epd) usb_endpoint_type(epd) usb_endpoint_xfer_bulk(epd) usb_endpoint_xfer_control(epd) usb_endpoint_xfer_int(epd) usb_endpoint_xfer_isoc(epd) In some cases, introducing one of these functions is not possible, and it just replaces an explicit integer value by one of the following constants: USB_ENDPOINT_XFER_BULK USB_ENDPOINT_XFER_CONTROL USB_ENDPOINT_XFER_INT USB_ENDPOINT_XFER_ISOC An extract of the semantic patch that makes these changes is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r1@ struct usb_endpoint_descriptor *epd; @@ - ((epd->bmAttributes & \(USB_ENDPOINT_XFERTYPE_MASK\|3\)) == - \(USB_ENDPOINT_XFER_CONTROL\|0\)) + usb_endpoint_xfer_control(epd) @r5@ struct usb_endpoint_descriptor *epd; @@ - ((epd->bEndpointAddress & \(USB_ENDPOINT_DIR_MASK\|0x80\)) == - \(USB_DIR_IN\|0x80\)) + usb_endpoint_dir_in(epd) @inc@ @@ #include <linux/usb.h> @depends on !inc && (r1||r5)@ @@ + #include <linux/usb.h> #include <linux/usb/...> // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2008-08-06ALSA: snd_usb_audio: fix SB Extigy IR Remote regressionPhillip Michael Jordan
The support for the SB Extigy's remote seems to be broken in all recent ALSA versions, including 1.0.17. The driver detects the event correctly, then submits a URB to query the RC code. On the Extigy, the URB is submitted with a length of 2 bytes. My hardware, however, only replies with 1 byte, containing the correct RC button code. The current implementation discards this as being too short. (line 1784 of usbmixer.c) This patch specifies a "minimum packet length" in the remote control configuration. I've left the values for the Audigy 2/Live! the same as the packet length, as I'm assuming the existing code works with them. (I don't have the hardware to confirm) This fixes the Extigy RC support, e.g. for use with Lirc.
