UAC - how to detect overrun on EP hardware fifos

[gmikitiuk]

Hi,

I'm wondering if there is any possible way to detect that software is not removing(or copying) data from EP hardware fifo to some internals fifos which could lead eventually to data beeing overwritten? ie. tud_task() is stalled for any reason.

I'm implementing multi-channel audio and with multiple channels sometimes the audio is corrupted, even though no underrun/overrun has occured on upper layer(tu_fifo_overflowed() returns false).

Another option would be that it's the host that is unable to keep up with packing the data in. This one is a little bit harder to verify without proper usb analyzer most likely.
