I tried that. After many failed commands, it finally creates
/dev/dsp. However, when I try to open it,
if ((alts->endpoint[0].bmAttributes & 0x0c) == 0x04) {
if (alts->bNumEndpoints < 2 ||
alts->endpoint[1].bmAttributes != 0x01 /* ||
alts->endpoint[0].bSynchAddress == 0 ||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
### this test seems to fail ^^^^^^^^^^^^
alts->endpoint[1].bEndpointAddress !=
(alts->endpoint[0].bSynchAddress | 0x80) */ ) {
printk(KERN_ERR "usb_audio: device %d
interface %d altsetting %d invalid synch pipe (format_out)\n",
dev->devnum, u->interface,
fmt->altsetting);
printk("usb_audio: %d, %d, %d, %d\n",
alts->bNumEndpoints,
alts->endpoint[1].bmAttributes,
alts->endpoint[0].bSynchAddress,
alts->endpoint[1].bEndpointAddress);
return -1;
}
As you can see, I commented test out, but still no go
