Subject: ALSA Support for Roland Gaia SH-01
Date: Sun, 20 Nov 2011 19:24:48 -0500 [thread overview]
Message-ID: <1321835088.14960.22.camel@darkside> (raw)
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.
