Yes for me, using a udelay(2) does seem to work. I have made sure that a usb device is still detected on the Jetson TX1. However, I am not sure the best way to test this thoroughly. If we do make this change it would be good to propagate downstream as well to get wider testing. Cheers Jon -- nvpublic
