As the release of Fedora 26 is quickly approaching I wanted to backup my hard drive on my laptop (currently running Fedora 25). Now it may be that the hardware is getting a bit old but I always had some trouble dealing with the USB slots on the laptop. This time, however, plugging in the external hard drive for back up did not work in the sense that the system did not see and did not mount the new media.

Here is the output of dmesg or at least the relevant parts:

[ 7.621287] usb 2-1.1: new high-speed USB device number 3 using ehci-pci
[ 8.049269] usb 2-1.1: new high-speed USB device number 4 using ehci-pci

Any help appreciated!

Maybe a faulty usb cable/connection. You can try a different drive enclosure.

Could you also run in a terminal udevadm monitor and then plug the USB at the specific port and check the output ?
