The current alsa rate feedback rate feedback format is
12.13 in 4 bytes. Clemens has a patch to make the rate
feedback format automatic such that it will work with
10.14 16.16 or any other formats. We are still testing the
patch put . Currently with 12.13 format rate feedback
Mac OSX can work with 10.14 and 16.16.
However, I think your problem lies elsewhere .
For example, AT91SAM7 has a limitation of EP siE of 64
bytes for EP 3 used for ISO transfers. There may also be
a limitation in that the Same EP number cannot be used
for both IN and OUT.
