I seem to remember this sort of thing being discussed in the past, e.g: Could the USB input of an Audiolab M-DAC be used without a USB HUB when connected to a Wandboard. IIRC the problem was about hardware which supported "Asynchronous mode", but was *not *USB Audio Class 2. A quick look at the Epiphany Acoustics EHP-O2Di would suggest it uses the same USB SA9023 receiver chips as the E-DAC 24 bit Miniature USB DAC. This receiver chip is supposedly Asynchronous, but is not USB Audio Class 2 compliant. So, I think the answer is there is no way to avoid using the hub with the O2DI. ------------------------------------------------------------------------ Krisbee's Profile: http://forums.slimdevices.com/member.php?userid=59080 View this thread: http://forums.slimdevices.com/showthread.php?t=101624 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
