Hi,

I recently started to use an USB 3.0 card to plug in an external drive
(using 4.14.x). So xhci does its thing and everything works fine, but
I get curious error messages after unmounting & removing a device, which
don't appear when unplugging something from my internal USB2 port:

[Jan 9 10:46] xhci_hcd 0000:03:00.0: Cannot set link state.
[  +0.000003] usb usb4-port2: cannot disable (err = -32)
[  +0.000001] usb 4-2: USB disconnect, device number 2

Are these messages intended or just a hardware hiccup on device removal?

thanks,
Holger
