Later we detect that EP is error and we reconfigured it ? There is an issue, an OUT transaction that doesn't get ACK'ed - right, and that is not a problem of the XHCI controller to send ACKs. My patch should improve the recovery sequence that follows, so that DATA0 appears instead of DATA1 as the first packet after the USB mass storage reset sequence. Please verify using Beagle USB analyzer. .--HPS
