Is this a problem in uaudio or in the USB code? If it is the former, =20 can you please point out the code in question in a way that someone =20 without knowledge of the USB system is able to fix this? If it is the =20 later, would you please tell Warner about it in a way that he can =20 investigate this (I'm sure you can tell if the fix is a =20 nearly-one-liner and where it needs to be done). We are approaching =20 the release of 7.0 and it would be nice if easy to fix bugs which are =20 known are fixed until then. > Secondly, full-duplex was not working with OHCI hardware, right? AFAIK: yes. This may or may not an issue in this case.
