What "xhci-tegra 70090000.xusb: can't get usb3-1 phy (-517)" means?

Hi,

I got the message “xhci-tegra 70090000.xusb: can’t get usb3-1 phy (-517)” in the kernel log, how do I troubleshoot it, what part of the device tree to look at?

Thanks.

I see that as well, but my USB works. I’m thinking (speculating) perhaps this is just that there are many ports/PHY and controllers and they are configurable…the software will likely give error messages for configurations not used. Are you seeing USB errors or problems?

Not at all. Everything seems to work well. Thanks
