But there is no difference and I saw the HW died in the log messages. However, we ordered another NEC host PCIe add-on-card and received today. I tested the just received NEC host and it is working fine for large data transfers from host to device. The device also works fine when I set max_sectors to 960. However, when I test the just received PCIe add-on-card with my UASP driver for queue depth 2, then it fails. The IN transfers are working fine but OUT transfers failed when queue depth is 2. There is no response from the host controller after some writes. When I looked into the kernel log messages I found the xHCI driver submitted the data to the host controller, but host controller does not generates the interrupt at all for that data transfer. Please let me know if I am wrong.
