Tool/software: Linux
Hi all,
I have tested our USB to serial products which use TUSB3410. There is a possibility of packet loss when I test with USB3.0 hosts (xHCI driver), but it tests normal when using USB2.0 hosts.
It is very easy to reproduce when transferring large data size (8KBytes) with USB3.0 hosts
Both Linux Kernel 3.11 and Kernel 4.13 have the same problem. Furthermore, I have tested by connecting the USB Protocol Analyzer tool, it shows that USB host sends entire data to the device without packet loss, but the device lose the packet to send. So I wonder whether it is the compatible issue for TUSB3410 with USB3.0 hosts.
Best regards,
