+ * NOTES:

+ * - async unlink should be used for avoiding the sleep inside lock.
+ * 2.4.22 usb-uhci seems buggy for async unlinking and results in
+ * oops. in such a cse, pass async_unlink=0 option.
+ * - the linked URBs would be preferred but not used so far because of
+ * the instability of unlinking.
+ * - type II is not supported properly. there is no device which supports
+ * this type *correctly*. SB extigy looks as if it supports, but it's
+ * indeed an AC3 stream packed in SPDIF frames (i.e. no real AC3 stream).

- * 2.4.22 usb-uhci seems buggy for async unlinking and results in

- * - the linked URBs would be preferred but not used so far because of

- * - type II is not supported properly. there is no device which supports
- * this type *correctly*. SB extigy looks as if it supports, but it's
- * indeed an AC3 stream packed in SPDIF frames (i.e. no real AC3 stream).
