LPC4370 high speed USB isochronous transfer

Hi, 

 

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.

Hew
