https://bugzilla.kernel.org/show_bug.cgi?id=219111 --- Comment #22 from Alan Stern (stern@xxxxxxxxxxxxxxxxxxx) --- It doesn't help. It shows that the device provides one input and one output stream, plus a MIDI connection -- no more. And it also shows the device claims to have only one configuration, not two. (Plus it shows Windows setting the data rates to 44100 samples per second, whereas your earlier Linux usbmon trace showed the data rates being set to 48000 samples per second, but I assume this doesn't matter much.) Are you certain that the device has two input and two output streams under Windows? The USB packet capture gives no indication of it. Also, how does the device behave under Linux if you set the old_scheme_first parameter to Y? In comment #6 you didn't say. -- You may reply to this email to add a comment.
