- *  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).
