397	Damn. i should have used a constant #define FWISOUND_MAX_SAMPLES 475 That from Clemens Ladisch's RE: https://github.com/torvalds/linux/blob/29b9667982e4df2ed7744f86b1144f8bb58eb698/sound/firewire/isight.c#L45 The hard upper bound from the packet size would be (2048 - 16) / 4 = 508 . But i didn't want to diverge . We can retry it in another round later with 508 value. (maybe it was a isight firmware in that time, or simply an Apple quirk.
