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  .

Maybe the PC has a Gen-1 PCIe slot, and the eval board has a Gen-2 slot?
Gen-2 is twice as fast as Gen-1.


Yes, This seems a point. My eval has Gen2 for sure. I will check with PC. Thanks.
