This patch is based on 3.8-rc1. It fixes two things: 1) A kernel panic caused by incorrect allocation of a u8 variable "bootresponse". 2) A noisy dmesg (urb status -32) caused by broken pipe to an invalid midi endpoint. It is also a little cleaner because there is no need for a new QUIRK_MIDI type as suggested by kernel developers, since the device follows exactly the MIDIMAN protocol. Signed-off-by:

This patch is the result of a lot of trial and error, since there are no specs available for the device. Full duplex support is provided, i.e. playback and recording in stereo. The format is hardcoded at 48000Hz @ 24 bit, which is the maximum that the device supports. Also, MIDI in and MIDI out both work. Users will notice that the S/PDIF light also flashes when playback or recording is active. I believe this means that S/PDIF input/output is simultaneously activated with the analogue i/o during use. But this particular functionality remains untested. Note that this particular version of the patch is so far untested on the physical hardware because I have not compiled a full kernel with the changes. However, extensive testing has been done by many users of the hardware who believe other versions of my patch have worked since circa 2009.

The commit [88a8516a : ALSA: usbaudio: implement USB autosuspend] added the support of autopm for USB MIDI output, but it didn't take the MIDI input into account. This patch adds the following for fixing the autopm: - Manage the URB start at the first MIDI input stream open, instead of the time of instance creation - Move autopm code to the common substream_open() - Make snd_usbmidi_input_start/_stop() more robust and add the running state check Reviewd-by:

Commit 88a8516a (ALSA: usbaudio: implement USB autosuspend) added autosuspend code to all files making up the snd-usb-audio driver. However, midi.c is part of snd-usb-lib and is also used by other drivers, not all of which support autosuspend. Thus, calls to usb_autopm_get_interface() could fail, and this unexpected error would result in the MIDI output being completely unusable. Make it work by ignoring the error that is expected with drivers that do not support autosuspend. Reported-by:

This is V2 of the patch, after feedback from Clemens and Daniel. This patch adds SuperSpeed support to the USB drivers under sound/. It adds tests for USB_SPEED_SUPER to the appropriate places that check for the USB speed. This patch has been tested with our SS USB3 device emulating a set of Yamaha speakers and a Logitech microphone, but with the descriptors modified to add USB3 support. It has also been tested with the real speakers and microphone, to make sure that USB2 devices still work. Signed-off-by:

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:

Here's a patch that adds MIDI support through USB for one of the Access Music synths, the VirusTI. The synth uses standard USBMIDI protocol on its USB interface 3, although it does signal "vendor specific" class. A magic string has to be sent on interface 3 to enable the sending of MIDI from the synth (this string was found by sniffing usb communication of the Windows driver). This is all my patch does, and it works on my computer. Please note that the synth can also do standard usb audio I/O on its interfaces 2&3, which already works with the current snd-usb-audio driver, except for the audio input from the synth. I'm going to work on it when I have some time. Signed-off-by:

Kernel 2.6.18 broke the MotU Fastlane, which uses duplicate endpoint numbers in a manner that is not only illegal but also confuses the kernel's endpoint descriptor caching mechanism. To work around this, we have to add a separate usb_set_interface() call to guide the USB core to the correct descriptors. Signed-off-by:

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. Signed-off-by:

This patch extends 42a6e66f 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. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/ ) // <smpl> @@ struct usb_endpoint_descriptor *epd; @@ - (usb_endpoint_type(epd) != \(USB_ENDPOINT_XFER_CONTROL\|0\)) + !usb_endpoint_xfer_control(epd) @@ struct usb_endpoint_descriptor *epd; @@ - (usb_endpoint_type(epd) != \(USB_ENDPOINT_XFER_ISOC\|1\)) + !usb_endpoint_xfer_isoc(epd) @@ struct usb_endpoint_descriptor *epd; @@ - (usb_endpoint_type(epd) != \(USB_ENDPOINT_XFER_BULK\|2\)) + !usb_endpoint_xfer_bulk(epd) @@ struct usb_endpoint_descriptor *epd; @@ - (usb_endpoint_type(epd) != \(USB_ENDPOINT_XFER_INT\|3\)) + !usb_endpoint_xfer_int(epd) // </smpl> Signed-off-by:

When CME keyboards send a SysEx message (e.g. master volume), the USB packet uses a format different from the standard format.
