Hello Tim, thanks for answer.
Few minutes after I send previous message I remove last two endpoints (Iso) and
now SetAltInterface working as
expected (in libusbx and libusbK). "My firmware" is not my, it is generated by
Atmel ASF. I only add debug console.
Now I have working Interrupt (for commands) and Bulk endpoints (audio stream),
both 64 byte but with Iso EP problems returns.
I managed to loop through uC stereo audio stream 48k/24bit using Bulk transfer
but on higher rates audio is choppy. Atmel controller is only full
speed capable, is this my problem? This is only for learning, final application
is SDR radio with 192k/24bit (or higher) rates.
Many USB 2.0 FullSpeed sound cards are capable of 192k/24bit so 12Mb/s is not
bottleneck.
