No simultaneous in & out USB audio with lib_xua

[Jash]

Hello,

Thank you for this new idea, I checked out the MCLK counts at each SOF period and it is approximately 3072 (3071 or 3073 from time to time), just like you said.
By the way, I use pin X0D11 as tile 0 clock input looped back from internal PLL on X1D11 (I didn't do it at first a few months ago and the USB device wasn't even recognized)

I also added some printf at ep_buffer.xc line 509 and at decouple.xc line 897 to know when an input stream is requested by host: input stream is started (in XUA_Buffer_Ep() then in XUA_Buffer_Decouple()) two times when I try to record the mic inputs.

I did the same at ep_buffer.xc line 820 and at decouple.xc line 1091 to know when the device has sent a packet to host: this is never reached (both in XUA_buffer_Ep() and XUA_Buffer_Decouple()), so the mics datas from audiohub don't reach the buffer, even if the request from host has been received.

Does it make you understand what could be happening?
