issues when connect to intel usb3.0 xHci onboard (Z77)
I am trying to use a onboard USB3.0 interface from intel chipset Z77 (Mainboard MSI Z77A-G45) with the FX3.
This USB3.0 xHCI Host always tries to set the device into low power mode U1. Why? If I reject that, then my application runs. But in the case it runs, the performance is worse. The link is connected through USB3 super speed but the reached speed without transfers is equal to a USB2.0 high speed connection.
