LPC4370 high speed USB isochronous transfer

Has anyone successfully do a high speed USB isochronous transfer on the LPC4370 ? I have tested the AudioInputDevice example which works in full speed. However when set to high speed, it does not work. Have been trying a few days to figure out why but to no avail. Enumeration in high speed is successful and Windows XP detected it as a audio device. However, when recording is done on the audio device, no data is returned. The associated isochronous endpoint is primed but no transfer complete interrupt is generated.


Thank you.
