All,
Can someone please help to add ALSA support for the Roland Gaia (SH-01)
Synthesizer?
http://www.rolandus.com/products/productdetails.php?ProductId=1074
I started a sample patch for usbquirks.h (see below) but am not sure if
the USB_DEVICE address is correct or what to use for the types. What
should the quirk table entry look like for this device? Does quirks.c
need a special case added?
{
/* Roland Gaia SH-01 */
USB_DEVICE(0x0582, 0x0111),
.driver_info = (unsigned long) & (const struct
snd_usb_audio_quirk) {
.vendor_name = "Roland",
.product_name = "Gaia",
.ifnum = QUIRK_ANY_INTERFACE,
.type = QUIRK_COMPOSITE,
.data = (const struct snd_usb_audio_quirk[]) {
{
.ifnum = 0,
.type = QUIRK_AUDIO_STANDARD_INTERFACE
},
{
.ifnum = 1,
.type = QUIRK_AUDIO_STANDARD_INTERFACE
},
{
.ifnum = 2,
.type = QUIRK_STANDARD_MIDI_INTERFACE,
}
},
{
.ifnum = -1
}
}
}
Below is the output of 'lsusb -vv' for the device. Please let me know
if additional information is required.

That doesn't look too bad except for a syntactial error in the MIDI
block (an extra "}"). Did you try it? What was the result?

This might need to be QUIRK_FIXED_MIDI_ENDPOINT maybe?

Yes; Roland's MIDI interfaces use different descriptors.

...
{
.ifnum = 2,
.type = QUIRK_MIDI_FIXED_ENDPOINT,
.data = & (const struct snd_usb_midi_endpoint_info) {
.out_cables = 0x0003,
.in_cables = 0x0003
}
},
...

Thanks for the help everyone. I was able to get the device's USB audio
and MIDI to work, but need additional time for testing and tweaking of
the code.
Here's the patch so far, please let me know if there are any other
enhancements I should consider.
{
/* Roland GAIA SH-01 */
USB_DEVICE(0x0582, 0x0111),
.driver_info = (unsigned long) & (const struct
snd_usb_audio_quirk) {
.vendor_name = "Roland",
.product_name = "SH-01",
.ifnum = QUIRK_ANY_INTERFACE,
.type = QUIRK_COMPOSITE,
.data = (const struct snd_usb_audio_quirk[]) {
{
.ifnum = 0,
.type = QUIRK_AUDIO_STANDARD_INTERFACE
},
{
.ifnum = 1,
.type = QUIRK_AUDIO_STANDARD_INTERFACE
},
{
.ifnum = 2,
.type = QUIRK_MIDI_FIXED_ENDPOINT,
.data = & (const struct
snd_usb_midi_endpoint_info) {
.out_cables = 0x0003,
.in_cables = 0x0003
}
},
{
.ifnum = -1
}
}
}
},

John F Leach

The patch's content seems to be fine, just make sure you follow the
rules described in Documentation/SubmittingPatches when posting the
final version. git helps a lot in the preparation :)
