I wasn't entirely sure about the quirk syntax as the two interfaces are at EP
4 and EP5. Does this mean I need to ignore the (non-existant) lower
interfaces? Here's what I came up with:
{
/* Boss JS-8 Jam Station */
USB_DEVICE(0x0582, 0x0109),
.driver_info = (unsigned long) & (const struct snd_usb_audio_quirk) {
/* .vendor_name = "BOSS", */
/* .product_name = "JS-8", */
.ifnum = QUIRK_ANY_INTERFACE,
.type = QUIRK_COMPOSITE,
.data = (const struct snd_usb_audio_quirk[]) {
{
.ifnum = 0,
.type = QUIRK_IGNORE_INTERFACE
},
{
.ifnum = 1,
.type = QUIRK_IGNORE_INTERFACE
},
{
.ifnum = 2,
.type = QUIRK_IGNORE_INTERFACE
},
{
.ifnum = 3,
.type = QUIRK_IGNORE_INTERFACE
},
{
.ifnum = 4,
.type = QUIRK_AUDIO_STANDARD_INTERFACE
},
{
.ifnum = 5,
.type = QUIRK_AUDIO_STANDARD_INTERFACE
},
{
.ifnum = -1
}
}
}
},
