there's a kernel patch in snd-bt-sco, and it would  be great if someone
could explain what it does:

*****

~ #ifdef CONFIG_BT_HCIUSB_SCO
~ 				case USB_ENDPOINT_XFER_ISOC:
- -					if (ep->desc.wMaxPacketSize < size || a > 2)
+					/* Use only the 9 byte
+					  "One voice channel with 8 bit encoding"
+					  endpoint until there is support for changing

+					if (ep->desc.wMaxPacketSize != 9)
~ 						break;
~ 					size = ep->desc.wMaxPacketSize;
****

Also, it would be interesting to know if this patch for kernel 2.6.4 is
still nessesary for newer kernels (2.6.6 to be specific), because I want
to "port" snd-bt-sco to alsa 1.0.4 and kernel 2.6.6.

thanks in advance,
