Hi All,
We are seeing following problem: Setup: We have connected a USB hub to DVEVM. We have connected two bulk devices mass storage and USB wireless device. We are continuously receiving data on USB wireless device (using iperf utility) and at the same time continuously writing to mass storage device. We do fsync () after writing data using write command to ensure data is actually written to mass storage device. Problem statement: In above setup we see SCSI errors and I/O errors. Also we have observed "usb 1-1.1: usb_sg_cancel, unlink --> 0" message sometimes. What is the significance of this message? Has anyone tested USB driver in such a driver?
