9 what led to this part of the usx2y module:
10 It provides the alsa kernel half of the usx2y-alsa-jack driver pair.
14 That memory is mmaped by jack's usx2y driver.
15 Jack's usx2y driver is the first/last to read/write pcm data.
19 snd-usb-usx2y which needs memcpy() and additional buffers.
21 standard alsa's snd-usb-usx2y period shaping scheme falls away.
24 plain usx2y alsa mode is able to achieve 64frames, 4periods, but only at the
34 Currently the usx2y jack driver provides above 2 services.
38 Currently rawusb dma pcm buffer transport (this file) is only available to snd-usb-usx2y.
