* 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).
