Log Message:
audio_open:
On full duplex hardware, the flags passed to hw_if->open() is always
(FREAD | FWRITE). But some devices (e.g. uaudio) check its
capabilities at open(), so unidirection devices like USB speakers
always return EACCES.
Avoid open() failure on such devices by checking the capabilities of
the device and changing the flags passed to hw_if->open().
