Hi Paul,

Thanks for the help.

If the host controller in your PC is not connected thru a PCIe bridge

guess.

Actually in both the case I am using single lane PCIe interface. I connect same PCIetoUSB3.0 card (tusb7340evm) with PC as well as with eval board .


A faster CPU doesn't help if the hardware cannot keep up.

Yes.


One thing you could do is try with a higher value for '-g' on the test
command line. That will make the usbtest driver use more scatter-
gather entries when it does the DMA. Perhaps that will help.

will try
